As mentioned, there is no requirement for an inspection. However, having people look over your work and doing so often is a good idea. I worked through much of my build alone but things went much better (and with more confidence) when I moved to the hangar and suddenly had many sets of eyes on the project. I was a bit shy about my work at first but now I invite all and sundry to look in. TCs do write reports submitted to the EAA but they need not be the sole source of your guidance. Other builders can have useful insight, even if they are building something different. A&Ps are also helpful; who better to advise about aircraft construction and repair methods?
Getting connected to people to help can be fairly easy; for me all it took was moving to the airport. But I could have done it sooner if I had known - in Flagstaff there is a good aviation community. There are a group of pilots who meet regularly for lunch and fly somewhere for breakfast nearly each Sunday. Many are members of the local EAA chapter. Once I started hanging out with them, I got plenty of interested onlookers. If a local IA dropped in to check out my project, it was due to interest and no charge to be but invariably I could talk out problems and get suggestions, just like I could with any of the other visitors. Heck, I even got my BFR current and one of the locals (AZTAILWIND on this forum) took me up in his -6A to get me proficient and also did my initial test flights.
So my suggestions is to root out the local aviation community NOW. It's never too soon and you can't get too much. This gives you more resources than simply inspection; you can draw on them for help when you need a second set of hands as well as the training I mentioned above. The final key is to make yourself available. Helping others is great practice for your own project and seeing how others approach problems may give you ideas for your own build. Some people eschew the interruptions because they take away from your building time but I think the general quality and richness they give to the project is worth it, not to mention the inspiration when things bog down, as they inevitably do.
