If someone wants you to hire them to research for you and their website includes:
- No physical address (not even a PO Box).
- No real indication of their experience. A "we've researched at several courthouses and been the Family History Library once" does not count as an indication of experience.
- Recommendations that are anonymous.
- No real name of the researcher.
What I am saying is that I personally would not hire someone for whom I have no real name, no address, no good idea of experience, and vague references. If you want me to hire you, I need some specifics about what you can do, what experience you are, and how I can really contact you.
Do a little snooping before you hire someone. Anyone can make a web page that indicates they are a professional researcher.
