Bagsmom,
I would just put a small pump in the bottom of the pond with a prefilter on it so that the pump doesn't suck up any debris and run the pump outlet to a waterfall filter. Construct your own waterfall filter, don't buy one. Make it out of whatever is handy.
My Mom's neighbor built a waterfall filter for his really small pond out of concrete blocks and an EPDM liner with lava rocks inside the liner, then he just surrounded the blocks with wood, painted them and planted around it. It's an extremely crude and low budget method, but it looks great and it works fantastic.
