We normally base our prices on 1k per square metres, as a rough guide only with out looking.
You will get different prices, dependent on area etc, as you can see,but with the answers given you can take an average, best to place your job in post a job section on this site, My Builder and get a few tradesmen out to give you firm prices.
If you have a set of plans, drop them in to Travis Perkins, they will price it all up, including all your material list and itemised, if you use them for materials they may give you a discount.
Last time I used them was £70 for a house, so it may be cheaper for your garage conversion.
