Well, you did it wrong then. Unless you already had a partita Iva, we are talking about 5% tax on 67% of your income (depending on the activity you want to perform) plus about 25% inps for gestione separata with no ninum. That means that if you don't have taxable income from the Partita Iva, you are paying no taxes. The accountant is going to cost you less than 400 yearly if you pick a decent one (like the guys at fiscozen).

My advice is to do some more math and research and maybe being more open to advices ;)

By the way, opening an srl in Italy can be done autonomously without the need of the notary by following online wizards like the one from iubenda. It's kind of cheap and gives you limited liability. Saying that opening a company is complex makes me think you kind of don't understand how complex running a business is.
