161706 Youtube Clone Needs Tweaking

I'm using an [login to view URL] video share script and need a modification and a few tweaks. Because it is an extremely high traffic adult website([login to view URL]) the database tables have crashed a few times and site seems sluggish and screwy at times. The site has only been online 2 months and is receiving over 30,000 uniques and 1/4 million video views a day. All without any paid advertising! The site is preconfigured to accept Paypal as a payment option but Paypal does not accept adult content payouts! So aside from a few small bugs that need to be worked out I'd like the Paypal option to be converted to another payment center like CCBill or whatever! In lue of payment I would gladly give 20% of all future signups, a partnership if you will! If this isn't acceptable of course payment is an option as well. I'm just putting it out there as the site is very popular and could prove quite a lucrative venture! Thanks
