I got made redundant this week and it's now 100% photography for me.
Wish me luck.
Am so sorry Guy that you've been made redundant, so of course wish you every success in turning your photography into a thriving and rewarding business.
FWIW, I think you have a great attitude and aptitude, it's just maybe not ideal timing but once word of mouth works it's magic hopefully you'll have more work than you can handle and have to expand your business.
If you've never run any business before, do ask someone you know and trust as there are a lot of needless "gotchas", oh and some areas offer grants to small businesses when first getting established, so consider that too.
