To be honest, the $250 quoted is a reasonable price. Could I do it in a manual mill? Heck yah. Would I? F!!! no. I've got it around 36 min per to mill to a reasonable surface finish plus set up plus programing plus over head. Professionally I wouldn't touch it for $250. AnOldUR probably has the best price your going to find. Your other option is to find a Trade school with a CNC department and see if they would do it.
