How easy and without a legal entity to accept payment in a store on wordpress?

Question

Payment systems

There is a desire to create a simple online store with a small number of goods (up to 20), and I want to accept payment in the most common ways: cards, paypal, Yandex money, webmoney, qiwi. Payment gateways require a legal entity, inn and other torments. Yes, and to connect them, you need to have a little experience in php, which I rather do not have.
So the question is: is there a simple WordPress plugin to connect, write, send money and enjoy in three clicks.
Plugins like woocommerce, wp shop require some specific knowledge, which, as I said above, I don’t have.
Thank you.
