The February Issue of The Family Handyman Magazine has a great DIY project w/instructions on a DIY Basement Egress Window. Or try The March Issue of The Family Handyman Magazine which has a DIY project w/instructions on how to build a Terrace (basement) Window Well.
Check them out. If you know anyone that subscribes to them, borrow them. Or, try a library. Or at worst, order them for a few $$$. I think it will be $$$ well spent!
My best to ya and hope this helps.
