What fish would be best for a Salt Water Aquarium if I know I'll be away for a week

Hello

I've always wanted to start a Salt Water Aquarium. Had a fresh water
aquarium years ago, but the fish are boring in comparison. I'm an avid
diver, so very interested in a Salt Water fish.

I don't want to rely on anyone to come in daily while going away on
vacation. Maybe once during a week vacation to top off water, feed
frozen food, etc. 8 days is normally the max I'm away for (twice a
year) and several 3-4 day weekends throughout the year.

So....is it out of the question starting a salt water tank if I may be
away for a week here and there?
Are there certain types of fish that can get by without a problem on
flakes and an automatic feeder while I'm away for a week? Certain
types of fish to absolutely keep away from because they'll eat nothing
but frozen food?

Also....what would you consider the BEST book for someone getting into
a Salt Water Aquarium for the first time? Something that talks about
different types of tank set-ups, which fish can be put with which fish,
live rocks, etc etc.

Thanks so much!
Pam
