My advice as a full timer is to offer yourself as a free 2nd shooter to companies just outside your area. Everyone needs a hand if it's only for gophering. But be honest with them - don't pretend you're just a video enthusiast and then desperately scavenge for their best ideas. They'll have seen it all before and they will clam up.
The experience of shooting a few weddings will open your eyes if you think this will be easy. Wrestling with intoxicated gorillas is easy, weddings are hard.
Get at least a few freebies under your belt after that, just to fine tune your technique, then hit the biggest wedding show you can afford with a cracking showreel and go in (quality dependent) at the £750 mark to begin with.
As your experience and style develops this can be raised depending on demand.
If you need further advice I'm happy to help.
