An emerging hobby business makes enough money to warrant hiring some VERY limited services, but not enough money to hire a book keeper, a CPA, and any other services that a "real business" needs.
I converted a side-hustle into a "real business" that paid taxes for several years. It's not super hard to start a business as a beginner but you've got some hurdles to clear, more-so if you are selling durable goods as opposed to "apps". I made one single mistake while conducting out-of-state commerce that cost me thousands of dollars in one fell swoop: that was more than all the cash the business had on-hand. I had registered to do business in the other state and was trying to dot my i's and cross my t's and be above board, but the mistake was till mine though. I could have spent those same thousands of dollars to hire experts over the same course of time preventing all the wasted money, lost time, and headaches but my business would have made so little profit it would have nullified the reason to be in business as a real tax-paying business.
Along the way I began to see various things as "cost of doing business" which was useful. I was glad to have the experience, I reinvested heavily into the business to save myself time and effort. But I never made enough money to hire others to do anything that I could do myself. The "cost of doing business" part only works if you have regular positive cash flow too.
So again, you are trying to serve hobby businesses who are not profitable enough to warrant them hiring experts to dot their i's and cross their t's for them. They are correct to be afraid of lightly stepping into this world and you won't change that.
