Can you just make a Credit Card form and have it linking with your Marketpress Store, for Checking o

So i have this client that sells furniture and accessories and I'm using Marketpress to build them a store, well i recently found out they use First Data Gateway as their payment gateway and I already have combed the forums for a Payment gateway Add-on for Marketpress, but from what i found there is not. So my question is, Is there a way to have a plain credit card form to fill out at checkout through Marketpress without using a payment gateway at all. (They don't want to use Pay-pal)
And My clients over all goal was to just get credit card information sent to them and they process it through their merchant account.
