I do not use the 510. I do not like it, I find the 901/808 to be a million times more satisfying, maybe 510 with the new CE's, but other than that, no interest in the prizes. (other than juice, of course)
That said, I may be able to pitch you some ideas.
The main thing you mention is that you want to make a 'show'. By 'show', I understand you want more than just your average YouTube video. It sounds like you want to create e-cig related entertainment, which I find highly commendable.
There are many high-profile reviewers out there, like Grimm Green, Spikey, Smokey, Scott Bonner and many others (oh, TGWTF, where art thou?). Some are highly popular, but in the end, their videos are just reviews of X, Y and Z.
To make a show, you need more content than that. What I think you need is a steady stream of 10-15 minute
vaping shows that feature an amalgam of content.
Sure, you need the hardware reviews, since a lot of views come from that, but you should also include the following on every show if possible: Vaping news, industry commentary/interview, mail answers, modding tips.
So you should have a show that looks more or less like so:
4-6 Minutes: Reviews of Hardware, juice and carts/cartos; equipment comparisons; previews of upcoming new gear. Keep them succinct and include 2-3 per show.
1.5-3 minutes: Vaping news, including anything of interest to the vaping community. This can be actual news articles, research, patent filings, court hearings, etc. etc.
1-2 Minutes: Quick segment to answering mail from the public, as a quick nod to the viewers and a way to keep them engaged.
3-5 Minutes: Commentary on any developments, concerns or topics of interest for vapers (vaping in front of children, the FDA policies, safety of inhaling flavorings or any other opinion pieces) or an interview with somebody connected to the vaping industry in some way, like CASAA members, store owners, manufacturers and high profile reviewers/commentators.
2-5 Minutes: Modding tips of all kinds. From bedazzling a battery and fixing cart fillings to creating MAP/Gummy tanks and juice boxes. Some could run much longer (making a box mod), and in these cases, the tutorial should be split on several parts.
Once you have your content decided, you can decide on roughly what order you want to present it in. You don't need to stick to a certain order 100% of the time, but fan letters should normally be done in the last segment.
Deciding content is the easy part of starting a show, tho. Your next goal is to decide on the image and style you want the content to have. You want it young and dynamic? Technical and geek oriented? Adult and professional? Maybe a mixture of styles?
And then comes all the splash screens, logos, transitions, closings and background audio to worry about, as well as the people who will actually be in front of the camera. Whatever you pick for any of this, you want to make sure you have the polished look of a high production value, regardless of how much you are actually spending. If your videos are grainy, with poor lighting or bad sound, most people will skip them and move on to the next offer.
As a vendor, however, you have a very tricky problem: credibility.
If you advertise a lot or only focus on what your store sells, your show will be a store show only, with a very limited audience. Take Chris from GotVapes, for instance. He's a dynamite reviewer, but people know he speaks for GotVapes and their products, and therefore only watch his videos either with a grain of salt or because they own/want a product from that specific store.
If you want an actual show, suitable for a very broad vaping audience, what you need is to learn how to separate your store from the show itself. Sure, you can mention your store sponsored it and maybe give a bit of extra face time to new products you'll get in stock soon, but in the end you would need to acknowledge other vendors and their products with fair and objective reviews.
Contrary to what you may think, recommending somebody try whatever new exclusive Riva battery is being sold at LiteCig, LF, MadVapes or whoever else does not hurt your brand. In fact, it increases your credibility and establishes you as a balanced and caring vendor, which is important in a niche market that depends a lot on a sense of community and cooperation.
Of course, you only need to mention vendors when they have an EXCLUSIVE product. This will mostly apply to juice makers and the few branded e-cigs floating around, like Blu, Volcano and Halo. Otherwise, you can just focus on models and threads without having to mention vendors (and sometimes even manufacturers) by name.
