The reason that there aren't any such services for what you want is because:

1) The amount of time required in order to set up any multiboxing program is going to outweigh what you, or anyone else, is willing to pay.
2) A setup is never considered "done," and so you'd have to keep someone on payroll in order for them to keep updating your setup.

It's been over four days since you first asked, so you already had time to get started learning the playstyle. Good luck!
