All of the above are great suggestions. The only thing I might add is that you might want to come to central florida on a vacation and dive some of the more accessible sites. I'm not sure which states offer archeological training, but I know that Florida and South Carolina have state-sponsored programs that allow certification for work on some active sites. If I can find the link, I'll forward it to you.
