I see there are many free ones online, but none seem to suit my needs. If you know of one, let me know.

All I need is my own script, or a rotator that allows me to make multiple on one account.

Example: 5 sites in rotator #1 - under btc address XXXXXXXX2
7 different sites in rotator #2 - under btx address XXXXXXXXY1

If you are offering a script I think almost any will be alright.
