Can I remove Price from review

Hi Guys,

First off thanks you for your wonderful plugin. I was waiting for a long time. My problem is that we provide mobility solutions to our clients. The price for the service is variable and we can not show it on the page or review. Could you please make the price field optional or show me a way around it? All the service providers must be facing the same problem.

Thanks & Regards,
Roger Bowne.
