stewie there's a company on ebay who charge 70 bangers for bike delivery upto 100 miles-maybe you'll be able to work out costings from that.

most drivers charge £1 per mile i think thats for all the time they are carrying stuff.

Thanks guys, just been sorting out the headboard on it today, got driven inside by this bloody weather though

I charge $2 per km (~£1.6 per mile) for the Toyota if I have to pull it out of the shed and that covers all costs (including things like depreciation) and a little bit for myself. £70 for up to 100mi is borderline doing it for love if its near the maximum, you have to do a long return trip and your time and vehicle is worth anything. If the market will bear a flat rate price of £70 consider a maximum distance of say 40 or 50mi which will probably cover a good percentage of potential customers and either charge by the mile after the maximum or leave the long hauls for those who'll do it for peanuts.

Also consider looking at how a London cabbie charges.
