With my day time job (Engineering), when we need something done and don't have the time or expertise to do it ourselves, we get a contractor. You find a contractor with the right stuff (qualifications) and develop an agreement (contract) to deliver what you want at a specified price not to exceed X $'s while ensuring that you own the final product.

You save on all the overhead items and don't have to worry about any of that employer stuff. They deliver the project and you can then tweek it to your hearts content, reuse it over and over, etc..

One could also get more than one spouse to work in the family biz I guess, but there would probably be alot of overhead with that too.
