now for my question how much would it run to get this crap painted, fitted and molded side skirts
depends on where you brought your parts to get painted, how the fitment was of the parts (major or minor or no problems), the color and quality you wanted it painted, and how much competition that shop had in it's area - plus how well the shop knows it's shit (ask around in the regional forums for a professional shop in your area who has done this type of work before)
Here is a short article for you...https://www.celicahobby.com/forums/...Paint-Install-How-Much-Does-It-Cost.html
Here is an Octane front that fit so bad, it was never installed to his car...https://www.celicahobby.com/photos/celica/exterior/bodykit/kit_octane/
It was about 1" too wide and the fenders didn't match-up at all - needless to say, it fit horribly!
The K2 sides ride awfully high, so unless the fitment is perfect, they will also need to be molded - once you start molding, you will have to paint that whole area of the car to match (you might think about a whole repaint as an option)
here is an example of what you get when something is molded...
What I'm saying is that what you are asking is NOT unrealistic, but its also not cheap...
