so obviously i still have alot of time.
You might be surprised at how quickly the time will go by.
guess which colour pcb i'm thinking of?
Pink with green polka dots and purple stripes.
How easy would it be to do this
Somewhere between "nearly impossible" and "a five minute job", depending on YOUR skills and knowledge. Guess what you forgot to tell us.
are there any services that can do this specifically for arduino projects?
Of course there are. How much are you willing to pay, and how long are you willing to wait? I'll bet that it isn't news to you that there is a direct relationship between the two answers.
