You can either use a prosumer HDV camera such as the Sony FX7, or prosumer/professional MiniDV cameras that record in SD, such as the Canon XL1s (oldies, but goldies), as for editing, I'd recommend PC over Mac, just considering versatility and options. Have in mind that you'll need a super-duper fast computer (dual core or even quad core, 2 GB of RAM, lots of hard drive space), two good monitors, lots of accesories (lights, mics, tripods, bags)... so I'm not sure your budget can cover them all.
