Start a business

Hello,

A long time ago I was visited by the idea of ​​making money with the help of the Internet. I pondered various options and ways to make a profit online, read many articles, studied, made mistakes and the like. And in the end I stopped at the earnings from the provision of services.

I have an idea and idea of ​​what and how to sell, or rather, to provide services. I want to organize an online resource with paid services on it. I note that the services are performed by the site itself, what exactly it does, I naturally will not say. I found the tools and tools to start a business .

However, in legal terms, how it will look like I can not imagine. Can anyone tell what difficulties will be in this case. Is it necessary for this SP, PE or LLC, because the services can be used by organizations that pay for them? How to deal with taxes? In general, the whole entrepreneurial or, how to say, business part for me is a dark forest. Please give good advice on this. Who is acting in a similar situation?
