Hi Tom,
I've no real suggestions, but I think depending on what you want out of it, it could be a very long, slow haul you are beginning.
If it's just a "hobby" thing it may be fun, but if your intention is to earn money from it eventually I think it will be so hard it will be almost impossible.
It's a bit like the many local directories, who would use them when they have a few hundred entries when you an go online to Google.
I suspect that the only review sites that will be successful in the long term will be those that have big money to put into them at the beginning.
As Wheelers says above there's also other things to take into account including if it gets bigger how are you going to verify that all entries are legitimate (good or bad ones) You only have to look at sites like Argos (product reviews) to read ones that are so obviously false (people getting over excited with their new pot of floor paint etc).
Sorry to be so negative, but if it's just a bit of fun or to help the local community this needn't put you off ;-)
Cheers
Gerry
