The easiest and cheapest route is to find a nice set of USED 700c wheels, endless supply out there, and cheaper than just a set of spokes. Second cheapest option here is to head to the co-op, they sell new wheels at a very affordable price.
If you are set on building a set of wheels, be sure to use stainless spokes and brass nipples. Follow the Sheldon Brown wheel building instructions, step by step. They are excellent.
