Rusty,
Nice to see your enthusiasm, however, as one respondant commented, only a few days ago you wanted to join the Navy!!
The overwhelming advice given was to go to Uni first, try to get into the UAS and then take it from there. Being in the UAS will give you the best kind of "Work Experience" you can get, as with your limited knowlege at the momment, a visit would probably just "Wow, you out"!!
If you still choose to ignore all this, then your best course of action, is to write to your local careers information office, explaining what you would like to do. Now, here's the problem: Hosting of a weeks long work experience will take someone a lot of time and effort, Not to mention the fact that someone will have to pay for it (Accomodation etc). So don't be surprised if you don't get very far. It's not that we don't want to, it's that everyone is so busy, that there just isn't people available to organise it.
Good luck, but don't be too disappointed if it doesn't work.
