I have a degree in Geology, used to be a geotechnical engineer testing mud and soil for the chemical and physical suitability for building on. But now I work for an international network selling commercial bandwidth to companies in carrier neutral datacenters. Always wished I had stuck with the practical stuff would be much happier tinkering and fixing things than writing proposals, best thing about my job is the interaction with people.
OP as mentioned think the best bet would be to find a company that will sponsor you through further education while you work for them, degrees are all well and good but now adays unless you have a first or minimum of a 2:1 at the other end of it you will struggle to see a massive advantage in a specialist industry. From someone who ended up with a 2:2 hardly any graduate scheme will be interested its too competitive a market!
