You can't slap those drivers into any kit and call it a day. A crossover specific to the driver needs to be designed and built. You'll also need to pair them with a tweeter suited to the mids' high frequency roll off.
The next hurdle will be funding a cabinet with a cut out perfectly matched to the driver's dimensions.
That said, Parts Express is a good place to look for prefab cabinets, both finished and flat packs. They also have all the tweeters and crossover components you'll needed.
