What should I use for an air compressor?

I've Been doing a lot of bodywork lately and run a 6" da sander I think it's rated at 10 or 13 cfm and my craftsman air compressor just can't keep up. I have an industrial baldor motor that's 2hp 1725 rpm it's a $1500 motor according to baldors site and it runs smooth and great. Do you guys think I can use that motor with the compressor I have? Or should I get a bigger 2 cylinder compressor? (by the way I have two I'd say medium sized tanks that are tied together) if I need a new compressor for that size motor what type should I get (best for the price I'm sorta on a budget)
