It's not hard. I'm an EE and I've wired two houses after studying the code on my own. I hired an electrician to check and sign off on my work, which was much cheaper than hiring him to do everything. The work I did was more code-compliant than work I've seen in other houses done by so-called "licensed" electricians. Possibly because I took the code literally and assumed compliance was non-optional.
