@Phillip Shafer I would try a couple of things:
1.) Go to a supplier of the products for each scope of the job. Example, find a tile supplier and ask them what would be a safe budget for tile backsplash and install. They will usually know because they have installers working for them. You are also not waisting their time since someone is in the showroom anyway. You can do this for roofing, siding, cabinets etc...
2.) Have your ducks in a row. Have approximate square footages for them and maybe a kitchen sketch. Doesn't have to be fancy just squares for the cabinets and appliance locations.
3.) Change your approach to contractors. Usually the owner is the one going out and pricing jobs and he feels like he is getting pulled in a thousand directions. Driving to a job and walking through it may be a hassle he doesn't really want. He may be more likely to help get some rough pricing over email if you ask to send him some pictures and a scope of work with approximate square footages. Ask if you could send him these and pay for his consulting.
I am a small general contractor specializing in remodels and my knowledge has value. I have quit giving that away and I hope more and more tradesmen/women do the same. I hope this helps.
It depends a lot on the area but if you have specific questions I would be glad to help in whatever way I can (without charge :) )
