Sounds like you have an interesting idea, though making it profitable will definitely be a challenge at first. Checking out Elasco (DTRO) would be good, but I am not sure how much 'financial' information you could glean from your trip.
By the way, I grew up near that area. Please be advised that we used to lovingly call it 'Garbage Grove' because it was one of the less desirable places in Orange County. While you are there spending loads of money, you can visit Knott's Berry Farm, Disneyland, Universal Studios, The Queen Mary (out by Long Beach), Catalina Island, and a whole lot more. I used to go to Newport Beach and Balboa quite a bit. Balboa has a little arcade and some neat shops and a car ferry. It is fun to go there at night and use the pits for a bonfire. Across the bay Corona Del Mar is a nice beach too. It tends to have some nice shells. I think California is a great place to visit, but I don't want to live there.
