I'll bet Camera Land can help you with anything you may want or need at a fair price.
The last time I was in Costco both the Canon and Nikon DSLR's were featured with two lens's, case, and both were under $600.00!
I bought a Nikon D3100 that will do all of things you want it to do from Costco (a few years ago), but would have bought it from Camera Land if I would have known then how good they are to deal with!!
Of course after awhile you will be wanting to go bigger and better!
Just my opinion,
