How To Find An eCommerce Apprenticeship/Assistant Job?

Hello Warriors,

I have been looking for a job as an eCommerce Clerk or an apprentice for a professional operation packing orders, responding to customer inquiries and the other rote tasks associated with selling physical products online, but I am having trouble locating one. I am not making this thread to beg for a job or a freebie, but rather for advice on how I can find someone with a professional eCommerce operation that I can gain employment with and perhaps more importantly, to learn from.

I currently operate an FBA account with Amazon as my bread and butter, with eBay and Etsy (vintage clothing) on the side. I am in my mid 20s trying to move out of my mother's house but I find that I cannot buy all the merchandise I need to make enough money for my own place being that I have numerous monthly expenses. It is also worth noting that I had to put my degree on hold (I am 12 credits away from my Bachelors) because of a lack of funds to pay off my tuition. I eventually want to go back but am focused on getting my Amazon business off the ground first.

I am specifically seeking an eCommerce position so that I can 1) earn the requisite money to put into merchandise and 2) learn more about how to run a large-scale operation. I live in a large city on the West Coast so the cost of living is high, but as an advantage there are several low-cost inventory sources nearby.

I am starting to think that the fact that I have my own eCommerce avenues is offputting to the prospective employers that I have interviewed with. Perhaps they think that I will leave once I get enough money, or that I will leave them to get my degree. In actuality, neither of those are very close to fruition being that I will need at least a couple thousand to make a big enough merchandise purchase to pay rent on an apartment and move up in my life. My target profit margin is 50% so I estimate I will have to put up at least $6,000 in merchandise monthly to make $3,000 in profit, which is just enough to live off of in my city with proper budgeting. I am current only pulling in $250-$500 monthly off of Amazon which is obviously not enough.

I realize that staying home and saving long term is the best option in terms of frugality, but I cannot stay here for another year. I love my mother but she suffers from some emotional problems and is very hard to deal with on a day-to-day basis. I got used to living without parents in college and being back at home is sometimes very depressing. But I will not quit.

Sorry for the ramble, but to put things simply I am looking for advice on how to find an eCommerce apprenticeship/clerk job in my area, a large city on the West Coast of the US. If any part of this post was unclear let me know and I will clarify what I meant.
