So you offer OWO /CIM, and these services do have risks. Not sure if you are fully aware of these?  You might want to read through on this site as there are threads on the subjects.  To give CIM for such a low rate, it's your choice, your choice alone.  But, punters know you are literally giving it away.

No one can tell you exactly what you should be charging, that is up to you to decide what you feel you're worth.

Have you worked out your bills etc?  That is a gpod way tovwork out your prices.

For example say you want to make 3000 per month, using half hours to work our the most you would have to see, that is roughly 17 clients a week at 45. Where as at 60 it is roughly 13 and at 70 it is roughly 11 clients.
