i'll be honest i would never consider paying to join a site that didn't give a free demostration of something beforehand.
The site is lacking a ton of required content. Also, your logo looks really jumbled. Make sure you have a Terms and Privacy page. Also, give out a few free reviews to post on your site as testimonials.
Backlink website...You should do well. I can't tell you how many times I have gone on search engines looking for backlink solutions. Good luck!
