As a Realtor®, I have contact with a lot of different professionals. If you need someone to pet sit, I know a person. (Whether she will have room in her schedule is another matter.) More likely you're looking for a good home inspector, lender, or A/C guy. Not only do I have knowledge of tradespeople I've worked with before, I also have a network of people in my office that can provide additional names and companies. That is just one of the many things a professional Realtor® like myself brings to the table. The internet is a great friend of mine in that it helps me help my clients, but it has limits--one of which is being impersonal. Let me be a resource beyond the internets limits.
