Unless you're incredibly lucky with eBay or have friends who're dumping equipment left and right, this is not likely to happen. Even if that's the budget after buying the frame, it's going to be hard.

A wheelset to match one of those frames would likely be ~$200 at the absolute bottom-of-the-barrel. You might be able to build a much better pair for a bit more.
Assuming you grabbed the one with the shocks, you're good there, but the other frame would need a shock (so it would seem, at least). Don't know how much that would be. Both would need forks - probably 6" forks at the bare minimum just looking at the frames. There's another $150.
After you grab wheels, you'll want some tires, figure $60 for the pair, minimum, plus tubes.
Then you still need a seatpost, a seat, a headset, handlebars, brake levers, shifters, grips, cabling, a crankset, pedals, a chain, a rear derailleur for both (a front derailleur for the second frame), and a casette.
