I am currently using Wordpress blog system ([url removed, login to view]) to power an independent music site. I need to customize and integrate into my wordpress database to have users pay monthly fees for premium content, but on a limited basis. For example, paying a $5 a month fee via Paypal gives you 10 download credits, and when you exceed the limit, you can buy additional credits for $1 per credit recharge (at $5 minimum for both non-subscribing and subscribing members), all based off the wordpress user database? Also there would be indication of credits left displayed somewhere, etc. I am fully willing to pay customization fees if this can be accomplished.
