Well there is the problem with paying someone a 'small amount' - any custom work is expensive and if you want it done well by someone you can go back to and complain to if something is not right then you are gonna have to pay a lot for it.
If you have the money pay someone. I wish i had a spare P4 laptop - my main Pc is only a P3 so i don't have the funds to pay someone to do my dash.
And bedsides - my car PC will be, like most people, a constant evolution of ideas that i will develop and modify and i woulod rather know how to modify my dash parts and get them looking back as they were the 1st time i 'finished it' everytime i cut a new section for something.
Also you have to find someone who is willing to take it on and are they gonna take as much care with your LCD etc???
