Don't forget having to spend $X000 for the privilege of being allowed to read the standards you're required to follow, and needing a consultant to tell you which standards you have to follow in the first place.
Hard agree that pricing for standards is generally insane. IMO if the law requires it, it should be free + maybe a $10 admin. Anything else is BS. Standards bodies already make a killing off their membership fees. There are alternatives and workarounds though, here is one: https://news.ycombinator.com/item?id=36452660
If you don't want to hire a consultant then don't. You can do it yourself. Go get a EEE degree and then spend 5-15 years working as a EEE in product development and certification. Then you'll be good to go :)
Or just blind self certify and pay the lawyers, Friendly Spectrum Agency and other spectrum users (like cell phone companies) when they come knocking and asking for damages from you.
