I know it can seem like you can't afford to turn down any work when you are starting out, but just make sure it really is worth your while and you don't end up bending yourself out of shape to accomodate all requests. It's amazing how flexible people can be once you set some boundaries...just saying (as one who has indeed tied herself in knots attempting to accomodate every last request from students) - amazing how a simple No can sometimes turn a "we can't possibly do that" into a "oh well, perhaps we can rearrange our other commitment"!
Totally true, and not just when you're starting out. I spent many years just taking on everyone and everything which came my way - in the end, many proved to be a either a false economy or a pain in the neck (usually both) - just not worth the bother. These days, it's either on my terms or it doesn't happen - I'm sorry if that sounds inflexible to anyone, but it goes some way to preserving my sanity!
If you are going to charge (which you should definitely do), you need to factor in the time travelling and the travel costs. I have a set hourly teaching rate, but if I do any work which doesn't require prep outside of the session or where there are little, if any other costs involved, I reduce this by 25%. This might (though I have no experience) be a way of establishing a rate for the time taken to travel there, with HMRC mileage on top. So, for me, if I travelled somewhere a couple of miles away and it took there and back about 15 minutes, plus mileage, I'd be adding about ?7 on top of the normal fee. To me, this doesn't seem that unreasonable, but really, I have no idea as all my pupils travel to me! Whatever you do, be very clear about it, be realistic about the time/costs involved, and stick to it to it applies the same to everyone.
