Yep. DIY. You can google/youtube the whole thing. If permits are required, and you are honest with your permitting agency, I haven't found one yet that isn't willing to help/work with you. But, I'll just let the wife keep getting 5-figure estimates until the light goes on...Updating this old thread. I got one quote for $48,000. Finally, today, grabbed the wife and went to BMO. Found exactly what we needed to put 6ft tall windows over the existing knee wall and a door in a 12x34 porch for less than $1,000!! Im in the wrong business.
