As some said, there is no way to set a fixed pricing rate for a service unless you describe in more details your requirements. Even so, no price is right or wrong.
As with anything, the lower you pay the less you get. The price will be directly related to the quality of the service you get. For some Resellers, budget is the main concern, even if their sites are down or have constant troubles while for others stability and support is the number one reason for which they prefer to pay more.
Regardless of the company you choose, just be sure to pick someone that will be there for you when things go wrong because there is nothing worse than not being able to inform your customers about anything when their sites are not working.
