Dan this is something many guys don't attempt to do. But once you get a set of guts and reed to honk. you will be very satisfied.
Last august (2015) I finally made up my mind to build my own guts and hand cut reed. I do follow Bob's process for the most part. Levi is a great source of info. He has let me bounce some thoughts off him. I am far from an expert but if I could help let me know.
I did make my own jig, this is a picture or #1 and I them made a 2nd one with a couple changes, and after I ground to much of a ramp on #1.
I have made a jig to help cut the wedges consistently but have not had time to make a set of guts to see how it worked. it just a piece of steel with a 5/8" hole drilled and cut about half the dia. of the hole off.
I have considered buying some reeds and using those but I keep thinking are they really my guts then? It would help the learning curve I am sure, but that is half the fun.
Have fun, take your time, you will enjoy it.
