i need membership script.. can anyone help me...

Hye
i want to setup a membership website with these features below. but i dont prefer plugin. i would like all-in-one script so i can install in my hosting. no wp / joomla plugins please.. thanks

1- basicly the script must support affiliates, recurring payments, online and offline banks.

2- for affiliates - referrer can see their downlines. i planning on using only 1 tier so that i can use paypal recurring.. but i also hope i can use alertpay also. and if affiliates can choose their affiliates username that would be a good bonus. i dont prefer affiliates modules/plugins like memberspeed script because when member register then they have to register again to be an affiliates. i need a script thats are build in ready.

3- for recurring payment - im looking for a script that can pays affiliates commission and site owner INSTANTLY. its ok with me whether when new member signup they have to pay the admins 1st and then to they referrer. or when they signup they have to pay to the admins and then admins will pay back to they referrer instantly using paypal. and i prefer all the transaction would be paid automatically using paypal.

4- for offline bank i prefer the script would notify the site owner when to pays the referer they commissions.

5- if the script can support forum integration and portal for members that would be a good bonus for me.. and also shopping cart for membes to promote they product.

i hope warrior members can help me in suggesting available script for this.. i hope the cost wont be so high around $100 is still affordable for me

the most similiar script is infinity downline...
