Ask HN: Individual print/mail as a service offerings?

I am looking for a company that would make it easy for me to get letters printed, and mailed for me, rather than my having to buy envelopes, stamps, and write addresses, etc.. I'm looking for individual mails (to extended family) not bulk mailing or anything like that. Being able to easily support/print quality color photos in the letter (like I can do at home) is a must.

Any suggestions?
