[chompy]

This might seem a silly question, but what should I charge sponsers?

I've approached a few places and they are asking for numbers.

Now I have an idea, but want to know if I'm way off or not?

Further info:
Beginner in motorsport.
Unlikely to win anything unless DaveP decides not to show up.
Mainly single event hillclimbs and possibly single event rallys.

Now my thinking is to build a pricing structure based on number of events and location of logos etc.

Does this sound ridiculous? Am I asking something that people won't answer? Am I being thick....
