so called "patch" systems are just scams. If you insist on doing it yourself, you should get a buddy, and both of you learn how to do it, and trade services on each other.
I would suggest that you purchase "The Blend Method" by Mike Bono published by Tortoise Press. Don't let the title fool you. The book gives excellent information on Galvanic, Blend, and Thermolysis. I would also suggest getting a used professional unit if you can.
