Babe, I really salute you and your hubby enthusiasm and determination to keep things under budget. Only 1-2 out of 10 couples would willing to go through such DIY. It requires lots of hard work + continuous creative juice flowing + teamwork from both partners. Keep the spirit going! You've really inspire me, and I'm sure many others too. Fits perfectly the saying "when there's a will, there's a way"

All the best!
