Select available pmt types for each product

I'm currently using marketpress with mycred points for payments. I would however like to be be able to also select a regular payment type like Paypal for products that I actually want to sell. is there currently a plugin that can do this, or can someone possibly help me out? This would also have to have the option to change the identifiers (ie points/dollars) and prefix/suffix in the post editor. Any suggestions?
Thanks all
