If you want to throw money at the problem here are my suggestions.
Find a good architect that knows the building codes and is at least educated in structural engineering.
Second, you can hire someone to manage the quality of the work. This can cost between 8-12% of the project bid. They make sure work is being done to a proper standard and will can deal with the contractor if something is lacking.
It is just going to take time. You can't build until you have permits. You can't get permits without a structural engineer drawings. You can't get a structural engineer until you have architect drawings. It all just takes time. Not to mention Our contractor was a year out.
Also, availability is still difficult on a lot of items. The windows we wanted were 26 weeks out. Our tile unavailable. If you like off the shelf junk from Home Depot, then you can avoid some of that waiting, but otherwise you have to simply wait.
Good luck!
