Hi,
I have a similar dilemma in that I used to work in TV in London before children. We wanted to move to a small village near Winchester, Hampshire to be nr our family, friends and for a better environment for the children. It effectively ended my television career as the commuting/childcare costs combined were just too high to make it feasible.
I had always enjoyed working and whist I love being a stay at home mum tremendously and my children are more important than anything, I really missed the stimulation of work and, to be honest, we were struggling without me earning. For the last two years I have been setting up a special events film company covering weddings, newborn video diaries, christenings etc etc. The work is building and it is definitely a challenge juggling children, housework, husband, setting up a business but it is definitely beginning to pay off.
I do tend to look after the kids during the day and work in the evenings/weekends but then if I had a job during the day for someone else's company I wouldn't get to spend so much time with the kids (we have two children - a 3 year old and a 1 year old). Everything in life is a bit of a tradeoff and this is just one of mine. I make sure I have at least one or two evenings a week off doing work to spend with my husband and he does shift work so he is away quite a few nights anyway. I get frazzled and sleep deprived sometimes... but at the moment it's all definitely worth it.
Business Link were invaluable to me when starting out, they emailed me loads of information on the basics - even down to the definitions of sole trader and limited company - so I could decide how to start out. They did do free business courses for people starting out although I'm not sure whether they do now (with the recession).
I've heard that having a Twitter account is key now for helping with your site seo. I am speaking to a marketing director next week about this and will post back when I have more info!
I also totally agree with Technoviking - do something you love! It's better to spend a bit of time finding out what that is rather than jump at something you're lukewarm about. You'll be spending hours and hours of your life on it and you have to truly believe in it, both for your own sanity, and also to be able to sell it effectively.
