Wizard of flight makes his templates public. He designed them and offers them for free. Nothing wrong with it when the maker says you can have them. I made a helmet from these templates. They are simple to use and noone will give you grief, ever, about it. He has templates for gaunts, jetpacks, helmets, pretty much everything for a fett/jango.
There are plenty of people here who ARE experienced in plastic work, but like brian said, experienced prop makers aren't likely to provide much assistance if they think you are going to essentially be stealing the work of another prop maker.
On this site, most of us do the work ourselves, or just buy from the propmakers that do the work.
The WOF templates are super easy to use and you can get a great base with very little time/money spent. They should give you what you need to do what your looking to do.
