I stand by my original post. Do not give away your work.

It sounds like you have built a solid start to your company, but it would appear that you are not where you want to be. Take a good look at your business model to make sure you are putting your time and effort into the avenues that will take you where you want to be. If you wish to be in those $250k houses, quit playing with builders that do condos. Find the right market and do your work with quality and professionalism and you will not have to worry about anyone even asking for free work.
