Do you know someone with a booster pack that can come and give it a jump start, if not, you can jump it from a car battery, better if you can do it with a car battery thats not on a car, so you have no chance of doing any damage.
Chances are your battery is fcuked after sitting there for all that time.
If the starter is just clicking, it either the battery or the starter, and i would put money on the battery.
Oh, and if you've been over there, cheers mate :wink:
