For a Coop manager to program each one of these boards it would mean having to install the ISP header and a capacitor for signal on the board, which would mean an added cost and time. I know that the whole programming aspect may appear intimidating but don't fret. Just roll up your sleeves and get after it.
With this hobby you have a learning curve that you have to be willing to take and you may run into the magic blue smoke (I've done it). But, that is what helps you learn and you learn more from a screw up and repair than you would if you had someone do it for you.
Long post short don't be afraid to roll up your sleeves and get after it!
