Costs of running a plane online

[Guest spriteah]

Im hoping that some people here can give me some idea at costs of running a plane.

 

I am considering purchasing a C172M IFR with 1400hrs to go on motor. So my questions are:

 

What money per hour am I likely to get if I place the plane online at a school?

 

I would need 100 hourly, generally how much do they cost?

 

I would need insurance approximately how much would that be?

 

On the other side of the coin can I rent it to just a 'few' friends and avoid many of the costs?

 

Any Advice would be greatly appreciated.
