I want you to act as a financial analyst and provide advice to her. Should she go ahead with the business, since she said it is serving as a side hustle or should she not even venture into it considering that she has no experience and even though she may be able to pay off the debt from her main job, her lack of experience may cause the business to fail ?
Non of the challenges that you have listed should stop her or non will stop a committed business investor. One thing is important which is her focus and resolve to survive in the business giving the prospect of the business and fishery is a good and viable business. It is lucrative because of its customer base.
My suggestion proper regarding the challenges of experience and fund are, there are consultants in fishery business that can help her through it. Those people are experienced people in the business, they can guide her. To funds, I understand that loans are not easy to get but she has to endeavour to get a loan. Finally, she doesn't have to give up the dream of being a fishery farmer.
