Hey M.B.:
I guess you have to look inside yourself and ask the question..."Why did I start this on-line business in the first place?" I understand that you started it off using the principles you learned in school, however, putting this amount of hard work into it just to give it up almost seems counter productive. One has to consider when owning a business that there will be risks, especially financially. I don't know what it took for you to start your business, but if you have others that are helping you currently, you might want to confide in them to see if they would become investors and/or owners as well. Or maybe seek investors from the outside if you wish to continue on with this venture. One of the biggest hurdles in business is the cost of doing business, whereas, when you receive price increases from your vendors, you must pass these increases on to your customers. The hard part is how much and when.
Do you have your coffee roasted and private labeled for you and then you distribute on-line? And if this is the case, do you have a good and steady customer base? If so, those are just the beginning stages. If you really like the business, then you will find a way to keep it going. But on the other hand if you truly feel that you've had enough and don't wish to continue then by all means sell. I agree with P56, if you have a passion for this, then jump in full time, but if you don't sell it out right and find something else to do. Only you can make that choice...
