Value of Internet Service Provider Lists

I'm the treasurer of our condo association (it's a small association, no outside management company). Normally, we rely on our maintenance man to maintain stuff around the building and perform other necessary tasks. Now, however, he is scaling back on some tasks, such as shoveling snow (he says he has a bad back and can't do it any more). Also, some of the service providers that he has recommended in the past haven't been entirely satisfactory (e.g. roofers and painters). We've come to rely on him, however, because, to be honest, we don't know much about hiring service providers. Speaking for myself, I bought a condo primarily because I didn't want to deal with those kinds of things, and I'm sure I'm not the only one in the building who feels this way.

Now I'm thinking we might benefit from getting on a list of service providers, like Angie's List, which supposedly has honest reviews from a wide range of customers. Those sorts of things cost money, though, so I'd need to justify the expense to the rest of the condo owners, and I don't have any experience with these lists. Are they worth it? Are there any no-cost alternatives?
