As a general rule of thumb, the key word is "developed". Each shop (unless they are a farmcode shop) should have a quality program, and one of the criteria of a quality program will be control and generation of procedures. Who, what, when, how etc is covered under that program. Those procedures should be under that program.
It sounds like you are looking to purchase a "can" inspection procedure. That is a dangerous route to pursue because any procedure will work best if it is tailored to suit your needs. I can sell you a “canned” procedure that would contain elements that have nothing to do with your product or the way your company operate.
If you want to write a generic VT procedure the is implemented by an individual inspector, I would start with ASME Section V to see what elements are included in the written procedure and what information should be included in the VT report. You can modify the recommendations to suit your particular needs.
There are times when you need to recognize your limitations, bite the bullet, and hire an outside consultant. It is best to work beside the "consultant" so you can learn from the experience and be better prepared the next time you encounter a similar situation.
