A possibly mad thought

Given various demands on my time, especially now work has become both interesting and busy, I think I'm mad for asking this, but here goes. I'm pondering whether I should seek occasional voice work, i.e. voice overs, trailers, adverts, computer games, etc. I have a fairly neutral and clear accent, at least I think so, and frankly I could do with the cash.

So, anyone have any comments (i.e. "You're mad, you are"), helpful criticisms (i.e. "You may not be mad") or (heaven forbid) a job lead? Even an agency address would do.

Thanks in advance.
