Sorry.... but I have to agree with DEAc23 about how long it will take to reach such a lofty goal, even tho you have lowered it since the beginning of the contest...
Unlike Facebook, the "Likes" here are a relatively new addition to the posts on the ECF, and very few people seem to bother 'liking' the OP in a Contest.
As a long-time member and self-proclaimed Contest Junkie, I don't think I've ever seen the OP get more than 20-30 Likes, let alone 750 different people entering... even in a long running one.
And getting 1000 posts can take quite a while even when the # of posts per person aren't so limited...
It would seem that you are a relatively new vendor to the ECF, and I really appreciate such a generous giveaway... also, as DEAc23 said: "...it's not like I'm going anywhere, so I can wait

"
I wish you the best of luck reaching your goals!!
Thanks!!
