How to start a Side Hustle in the US from India?

I am a Software Engineer living in a rented house in Bangalore. I don't have any property. I want to start a side gig of selling printed T-Shirts in the USA. I think I have some good ideas on design and I think it can act as a good side income. I tried some online websites that offer such services, but soon I realised I need more. I need a TIN number, a business bank account, company registration and trade mark, filing taxes- not sure about us india tax compliance rules.

I believe there will be a hell lot of other paper works that would be required. Now I just have some creative ideas that I want to give a try as a side hustle but thinking about setup I feel demotivated. I can bear the idea of what if the hustle fails, but I don't know what to do with trademark and business registration after the hustle fails, can I reuse it for some other kind of businesses?

Has someone tried or thought of trying such side ventures? I don't want to leave my job and do this.

Is there some subscription service available in India that helps setting up business where an individual like me can try his hand at various entrepreneurship and fail and fail fast and continue until succeeded ? Like, I would love it if all these heavy lifting of setting up business, auditing and taxes are taken care of by someone else and I just focus on the creative part.
