I would like to recommend "Crystal Wright's 1-Day Packaging Your Portfolio Workshop" DVDs.
http://thestore.crystalwrightlive.com/DVD_Packaging_Your_Portfolio_p/dvd01.htm

She has a book out that is probably very good as well.
For me the DVDs were a game changer.  $99.00 for four DVD's seems like money well spent.
I learned a lot from the DVDs on developing a plan, contacting people, connecting with people, and marketing myself. 
My favorite part of the DVDs was on the power of the Thank You Note. 
Do you know that many people will keep a thank you note with one of your images on the cover on their desk, long after they have discarded all the comp cards that people give them?

Your friend,
