Review your Website Quote

The Problem: As a client you have no idea if the quote you have received is any good. Is the price okay? what is it that you are going to get? Is there anything missing that could cost you more money down the track? Are there any additional questions you should be asking to ensure you get what you pay for?

The Solution
A service where a user can submit their website/development quote and have it reviewed by industry professionals. They would provide unbiased feedback to ensure the client understands what they are paying for and get the guidance to improve their outcomes.

Issues/Implementation
There would likely be some generic criteria that it should be checked against (terms and conditions, inclusions etc), probably a list of questions that would come up most times that may not be answered directly in a quote.
Most of the time it would require the industry professional to understand what the client wants in order to understand if the quote is acceptable, so this could be time consuming.
I guess the service would be billed as a one off, so not good for MRR.
But maybe there is another angle here to make money?

other things
I guess the other part of it is that you would get access to alot of proposals and be able to use that data to get ideas on industry pricing etc. Possibly be able to build other products out of that data, maybe a service where the developer, client and 3rd party work together to build out a proposal.

Anyone have any thoughts?
