Maybe post an RFQ on this site asking for programming services quotes. You just never know what the price will be until you ask. I suspect there are lots of hungry guys out there who will work at an affordable rate.
Now whether it will be handy to do this contracting out, I don't know. Probably sucks if you are in a hurry to modify a program and its late, or a holiday. Kind of puts your power as a shop owner in the hands of someone else, too. Not a good state to be in, IMO.
First you get good, then you get fast. Then grouchiness sets in.
