I have prosites and affiliates installed but I would like

I have prosites and affiliates installed but I would like to add solidtrustpay.com as well as paypal, is there a way to have that added, I will ofcourse be willing to pay for the addition. (I would like to offer egopay.com and payza.com too, down the line)

I figured I would ask you guys seeing as you know the addons before trying to find another programmer.

I thank you for your time,
Patrick
