I've done a few jumps solo, but I've not got any form of license.
Did it specify what type of jumps you have to do? Because there are at least 3 types of solo jumping you can do, and a lot of the time you can't solo straight away (I was lucky).
Also, I agree with fanpeople, not to mention base jumping. You need to be a really experienced skydiver to start base jumping, what with the added risk and all the different types of jumping that involves too.
I can answer a few questions about it, not much mind.
