Greenlancer will draw up code-compliant plans that you can submit to your local building permit agency, and they'll revise if anything needs it. It cost less than $400 last year. You've done enough research that they'll be able to easily take your project and turn it into something legal. I recently did an Enphase system of a similar size to yours. It was fully DIY except for wiring the combiner and a roofing company to plug all the holes I drilled. Working with PG&E was truly an epic year-plus battle culminating in a CPUC complaint, but in the end it was really just a bunch of emails. I don't have any installer recommendations, but it should be easy enough to find a local electrician, and I've found that they tend to know others in adjacent fields.
