Contract coding conundrum
I am getting into contract programing and I have a problem. Supposing I quoted a price (via email) and the guy accepts, then I realise the work is harder than I thought and the code could be licenced.
Is it legal to say "Sorry I've changed my mind, I'm coding this on my own now but I'll give you a free copy when it's ready."
If not, is it legal to say "Sorry something has come up and I don't want to work with you any more" but then code it for myself?
I have signed no contracts, spoken on the phone once and exchanged a few emails. I've barely started the code and we first emailed about a week ago.
