Some shops will build coils for you, but if you're going to use RBA's it's best to learn about them for yourself. First and foremost, get an ohm meter. The only way to accurately know what resistance a build is, is to test it, otherwise it's just guessing and hoping.
We can help get you started though. What batteries are you using?
Side note: The shop that sold you your equipment and built your first coils really should have taken the time to explain a lot of this stuff to you, for your safety, and their liability. Unfortunately many don't. I apologize if I sound harsh, it's just that you're using a potential pipe bomb, and I'd hate for you to get hurt.
ETA: for the five posts, they only need to be posts, replies count. Don't start multiple threads, especially on the same subject. They'll just close them and reset your post count anyway. Once you have five posts, the servers update at 25 minutes past the hour.
