monthly cost of access to MLS

[Michael V Akbar]

I am a total newbie and don't have my real estate license but I am being presented by few opportunities through friends and network and I find myself in a situation that need to do comps, etc. Does anyone know how much a real estate agent pays for their monthly usage of MLS? on the basis of that information I would like to ask a real estate friend to do certain amount of monthly searches for me for a fixed fee, and without expectation of being the agent of transaction. Appreciate any input. Thanks.
