I need a site that allows twitter users to gain followers like this [login to view URL] i just need something quick and cheap the sites only one page along with paypal intergration and twitter integration. The point of this site is to have a twitter account and as you log onto the site and sign into your twitter it logs you in and the site allows 48 people who have logged into the site via twitter to follow you but on the same hand the site uses your account to follow others. The site allows you to log back into the same twitter on the site every hour and a [login to view URL] premium part of site is so that if the users want unlimited followers which turns out to be like 500 or 750 for the day without following anybody else they can pay the price for it.
