Can Some one make me this Billing script?

[guitar riff]

OK The script i need written Needs to have the following.

Sufer can be billed in 10 min increments so say surfer a Buys 1 hr of time he can use it in say 3 differrent chats or all in one but the script needs to track time to each girl. So that they can be paid properly.

The following billing options need to be incorporated in it.IKOBO, e passporte, ccbill, verotel

also need a way to track sales from afilliates.
