Hello, please check my portfolio. I have been working with Flash since it was Macromedia Flash (someting like 7 years ago?) And, all the vector illustrations in my portfolio, are made with this program (don't really like illustrator).
Also, I can offer you some Action Script 2 Coding to add any interaction to your map if needed, for no more cost.
Please consier me, you will not be dissapointed!
Finally, I would be using CS5.
