Professional Organizations

I'm thinking about joining a professional organization for illustrators. I'd like one that will hold workshops or conferences and give useful information about marketing yourself, networking, insider tips...etc. What organizations do you belong to? Do you find the membership useful?

Looking for advice

I have always wanted to illustrate a children's book. I have the opportunity to work with someone who saw my blog and likes my style of work. One problem. He wants to know how much I will charge. HELP??? I have no idea how to price this sort of work. Do you charge for comps and finals. Do you charge for revisions? Is there just one flat fee?

This is a book for elementary school children and so far that is all I know. Thanks for any advice you can offer.

New Website

Hope everyone is doing well! No posts in a long time so I assume we're all busy busy with work. I know I am. :o)

Over the summer I took an HTML class to learn how to make my portfolio online. It was very basic because I am still very much a beginner in regards to web design. The first site was ok, but I know I will always want to improve it every few months. This weekend I redid the site and am looking for feedback. FYI, this is all HTML and CSS using basic Notepad. I don't know Flash or Java, and I don't have any new versions of Adobe products (yet).

The address is: http://www.lindsayjohnsondesign.com

I'm specifically looking for feedback regarding:
-layout
-ease of use
-that the text is all written in clear language
-suggestions for improvement

Thanks in advance!
