An enthusiastic D.I.Y person can easily imitate this tool I know of one man that filled his wheely bin with water (to make it stable) and practised with a small piece of vinyl. trimming off a couple of inches at a time until he considered himself good enough to attempt the real thing.

The TRUTH IS
The only difference between a D.I.Y. person and a professional is that the professional will be in and out of a job in no time.
The D.I.Y. person will do it over the weekend. Possibly buy a carton of beer with the money saved.
