Book Marketplace connection

I am trying to attach my marketplace website with Stripe/connect (see [login to view URL]) I have 5 or 6 scripts already written that just need to be adjusted so they will work: 2 will sign up sellers onto my site (one getting the initial information my site needs before the user moves to Stripe to create an account, and one they land back on to complete the process.) We need the user account number or private key or whatever Stripe uses so that the user can get paid for sales, as that is what we will use as the seller's ID in their inventory, the other 3 are to (1) create a customer object to charge buyers without making them enter credit card info every time, (2) actually charge the customer at purchase, the 3rd script encorporates the first two. NOTE: You do not need to write these scripts, the code is already there. I just need someone to proofread them, tweak them if necessary and do any testing, then send the corrected code back to me. Stripe/connect has testing keys to use so there is no need to obtain any login information. I would also like a script or 2 written up that would make it possible for the seller to issue a full or partial refund on their own, without having to go into their stripe accound to do it (something that could connect through a simple "refund" button to make it as easy for the user as possible.)
