Hi, you are right in the first part that of Setting Short term and long term GOALS.
You have not mentioned current sales or production available... This must be given first.
However first have you done test marketing of your product?
Have you taken at least a couple of hundred feedback from customers?
Once these two answers are there, you would realize that the offering is either meeting customer requirements or not.
Based on this you can set growth plans to either weekly sales or monthly sales and monitor on daily run rate required...
