I am venturing into the realm of providing support services for a number for specific machines and then also providing training on those machines. I am trying to get a feel for general hourly rates and call out fees to use as a starting point to work from. No I am not doing electrical or plumbing work. I have an opportunity to also put in monthly service contracts in place and I would like to make sure that I make good money from it.

The questions are:
1. What is the acceptable call out fee range?
2. What about traveling costs?
3. Are the call out fees different after hours - (price range)?
4. Does the call out fee cover a specific number of hours?
5. If the call out covers a specific number of hours what are the rates from there on if the job requires more time?
6. What would be a fair hourly rate for preventative maintenance?
