Check Lowe's or Home Depot. They have books with outdoor projects. OR, do what I do. Draw you own. I like that sort of thing though. Check out my home page. There's one on there that I built in 1992. I drove by a month ago and IT"S STILL THERE!!! Once you figure the rafter length/angle, it's not so bad. If you figure the time spent working on the drawing, you will see that $70.00 to $100.00 is nearly fair.
