I don't know what kind of engineer you are, but I know of a structural engineer who started his own home inspection LLC and will do both a home inspection and structural inspection at the same and he is making bank! I guess it depends on if you are well enough to be climbing up on ladders, roofs, and crawl spaces. We had him do a home inspection and his agreement is very thorough and protects him from liability if something is missed or inaccessible at the time of inspection.
