Login with Referral/Percentage

[gr23]

I just started a small clothing business and I'm working on the website right now; I've done all the easy stuff, next up is creating user privileges.  Here's what I want:

 

-Upon user login they will be directed to their "rewards" page, which shows the amount of store credit in their account.

-When someone else registers and buys something, there will be a field for "referral username".  Upon checkout, the account of the one who referred them will be credited 10% of that first order.  I have no idea how to put whatever credit is in their account toward a future purchase.

-Additional information block to be filled at user's convenience (shipping/billing).

-There will be credit card checkout, the code for which would be provided and, with a lil elbow grease, should fit nicely into my page.

 

I'm new to PHP and though I've found many useful scripts and tutorials, but tailoring them for exactly what I want is tough.  If this is a common question, please forgive me but I couldn't find it...not sure what to search for.  Essentially, I'd like to know if it's possibly with PHP and perhaps some ideas on how to construct the code.

 

I don't really have the cash right now that most companies charge for database creation/PHP coding, so I thought I'd try here to see if you ladies and gents could help me out.
