Amazon FBA business

Hello everyone,

I am currently working full time in a company. The hours are long (80+ hours) and I only make enough money to pay my credit card bill. I am looking to make extra money to save money for kid’s college funds. I want to seek our advice on a side hustle.

A lot of my friends are telling me about Amazon FBA. So I bought a couple of courses on it as well on Udemy and entrepreneur.com and start learning. I would like to seek your advice on the Amazon FBA business.

I am a very hardworking person and I am willing to put a lot of effort to make it successful. I would like to seek your advice on this business and any tips you have for me(dos and donts) and where to start. I also was recently reached out by NJX automation. Do you know if this is a legit company? Their proposal is they will manage my Amazon seller account and they guarantee profit the first year or money back. Have anyone tried this? They are asking for 30K for inventory, vendor contract, and consulting fees

Right now I am a bit confuse. I am not sure if Amazon FBA is a good business to start and if it is then whether to sell myself or hire a company like NJX automation.

Thank you!!
