I would happily recommend that any buyer make full use of your free sourcing service as it has proven very beneficial.

I just wanted to say a quick thank you for your help in sourcing me suppliers for a recent project I needed help with.

I found that by using your service I was able to find someone quickly and efficiently and was able to start business with a supplier I will continue to use.

I am so impressed with the way the last enquiry went, that I will be using you again shortly for another requirement for a different process.
