My best advice is to find someone who is doing what you want to do, and then offer to bring value to them (for "free") in return for mentorship, guidance, and knowledge. 

You are free to refinance out of the loan into another type of loan with no penalty. 

PO box or your attorneys office is typically the protocol.

Their website shows a downtown Seattle address that is likely a condo and not a business office.

They will fill in the lead submission for for FREE!.

Go to meetups, offer to help people FOR FREE, ask for book recommendations, read the books and follow up with the people who recommended them. 

There’s also the free advice from Rabbu that’s great.

They typically have a "designer" or "consultant" for free that can give advice (or research in your case) specific items.

Many companies I found do not want to cover a lot of homes because of the items you stated but with that the hurricanes and also in florida many roofing companies have done the "I will replace your roof for free, just let me deal with the insurance company".

As I understand it the PMI Franchise is rolling this out to all of there offices.
