Hi,
Consider what you really want to do. Load Control / Dispatcher requires load sheet certification whereas TC in most cases is managing the turnaround process and not planning the load or producing the loadsheet. You're more likely to walk into a TC role than Dispatcher/LC. Personally, I'd go for an airline over a GH. If you're prepared to invest a bit of time, think about joining an airline and keep an eye on internal vacancies. If you get the right airline you can be trained and certified in Load Control, the pay doesn't have to be shocking and its a hugely rewarding role.
Hope this helps a little.
