Any good reference business book/s for a small videographer/entrepreneur (weddings, events, corporate ...etc) ?

I have seen a lot of business books for photographers but nothing really substantial for people like us.

In my opinion (take it or leave it) I think that the photography books lend themselves to video. Much of the issues are the same. One book that I wouldn't do without is "Business and Legal Forms for Photography" by Tad Crawford. It has 31 legal forms in it that have been very useful to me and they are also supplied on CD in Word and PDF formats.

Now, the forms are slanted with a bias to the photographer, and the author does state that they are just a jumping off point for negotiations, but I have still found them to be invaluable.

Just my opinion...

Oh, and I have no affiliation what so ever with the book, publishing company, etc. - except I own a copy of the book.
