It depends on many factors. Why?

To answer this in a more resonable way....
Depends on..
1. What they will do
2. How they will do it
3. How much they want to do it.
I have not done anything yet, so I'd need a complete turn key building from ridge vent to fill and everything in between, otherwise I might as well do some of it myself and hire bits and pieces out. I can do that now.
I want the thing to be built with what I consider best practices, not what saves them time and materials. I've been told from a couple of builders, the truss supports are nailed to the posts. I mentioned notched beams or at least bolts, the response is usually, we can do bolts but that will be extra. Others won't tell me if the design meets local wind load requirements and I need to hire an engineer. I find it disturbing that a professional builder cannot tell me their design can or cannot handle a wind load.
I'm on a strict budget. I don't want them to tell me half way through I need to pay more, cuz it's not going to happen. My budget is my budget, if they cannot stick within that, then there is no reason to talk. That's not a dig on anyone, just reality. The reality probably means I am on my own. I understand they are in business to make a living, but I'm in the business of not throwing away money if I can sweat for it.
Way too many things have spiked in price over the last several years because people aren't able or willing to get off their butts and the "pros" are more than willing to take advantage of that. This of course includes the so called "kit designers" but the simple fact is, I'm not a structural engineer and so I need to farm that part out to make sure i don't build something that will kill me or anyone else (as long as I follow the plans).
