Customizing ZX5 Focus

I am kinda new at this stuff, but I really want to spend some money making my car look the way I want it to. I want to get the interior redone, right now its a light grey but I want it to be a very dark charcoal or black interior. Anyone know about the ballpark prices for getting the interior redone? I dont want anything really fancy just change to a darker color.. I am looking to get it painted and put a kit on it too. Ive been wanting to do this for a looonng time just didnt have the money or the resources. Now i want to start.. ive bought a few things for it already but the major stuff I need opinions on..

It would be cheaper to find a wrecked car with the color interior you want at a salvage yard. You could also replace the parts with new from the Dealer, but removing seat cusions and carpeting, etc can become very labor intensive.
