once again

, my little car is giving me grief. i brought her home from work on monday, put her straight in the garage, and yesterday morning when i go to start her up to go to work, i turn the key, and get absolutly nothing, my ignition comes on because my heater starts up. but apart form that nothing, the engine doesnt even make a sound. this problem happened a few months back, and after a bit of beat to the starter motor it worked.
but this time round it dont want to know. i can get it going every time bump starting it. but once your turn it off, and try to start, im back to square one.
:'(
there is me taking the 20-30 min walk to work in the mean time.
suggestions would be much appriciated

* cheers in advance
