Here where I live (Australia) it is near impossible to find good professional tradesmen. While it might be irrational on a financial level to spend my time painting or other trades, I get the quality I want by doing it myself.

Even on the financial level tradesmen here in Australia are so overpaid (compared to everyone else) that it makes sense even for me to do it myself. My house was painted by "professionals" just before we moved in (purple??) and it cost the previous owner $20,000. My wife and I repainted it white (this required 5 coats of paint) and it took us two weeks including the time I had to spend getting the purple paint off the windows and floors and patching all the holes that had been painted over.

Tip. If you are selling your home don't paint it some unusual color. I managed to buy my home $200K under its actual market value and quite a bit of this was due to the crazy way the place has been painted.
