VISA or ESTA to work for myself in the States?

[bagger]

I have an LLC (Limited Liability Company) set up in Ireland, that’s where my address is and where I pay taxes. I’m flying to the USA with an ESTA for 3 months. It was to visit friends, but now I’ve decided I’m going to set up an online clothing brand, with clothings sourced from China. I’ll buy a printer to put designs on the clothes and I’ll ship them out to customers in the States myself. VidMate

Can I do this on an ESTA? I don’t think I need a working VISA to work here, as I’m not working under a US company?

Any help is greatly appreciated.
