Painting My '03 Sport Trac

Okay so I have a silver '03 sport trac and i want it black. So i guess what im trying to ask includes a few things... :scratch:
1) What is the cheapest way to do this?
2) How much is this going to cost me?
3) How long does it take?
4) And is there any other stuff i need to be aware of when getting this done?

to change the color correctly (door jambs, engine area,etc) and using quality
paint I would guess in the neighborhood of $2500-3000 but thats just a guess.
