Ask HN: Site for reviewing Apps/Business Ideas

what do you think about the viability of creating a paid service where experienced web entrepreneurs could review your app/business plan and provide you with a paid unique report about what they think.

The reports would focus on all major areas such as, strength of idea, market site, UI, functionality, competitor landscape, monetisation options etc.

Would you be prepared to pay for this kind of service, taking into account the reports would be custom written for each app that was reviewed.

if you would be prepared to pay, how much for what kind of length report

cheers all.
