I would like to take this opportunity to thank you personally for all the support you have provided us over the past few months. 
I cannot recommend you or your company enough to people and would not hesitate to using your service again in the future if needed. 
You are reliable, always available and have been nothing but a pleasure to deal with. 
I can’t thank you enough for all the support and work you have provided us. 
Hope to do business with you again in the future. 
Thanks so much
