Sales and Marketing

I need some help with selling something. I have a very hard product to sale . It is a fish pond or lake product . Otters are one of many problems pond Owens have . Untill now a otter fence was the only fix . My patented product only takes one second to fix that problem humanly . Each county has a county extintion office that people go to for advice an help with there problems . This is where I need someone with very strong selling ability to write a very convincing letter that I can send to my county extinction office that mite help with my sells. I have made me business to know about everything there is to know about otters I can supply you with these facts if needed
