Startup business registration

Hello, Me from Chennai along with my friend from Delhi (not met directly) are planning to host a website service for which ideally there is no revenue generation through any source. I will be responsible for all the contents and my partner will be responsible for the technical aspects such as website deigning, digital marketing, etc. The website is basically about sharing knowledge for the parents. Though currently we will not receive any sought of income from the website, at a later stage we are planning to publish a book based on the contents for which we might generate profits and also have copyrights issue. At this stage, we should not have any kind of issue between us. Hence, we are planning to register it as a company. Considering the fact that there is no revenue for the company now, kindly let us know how we can proceed on this issue. We consulted an auditor regarding this and he gave us two options. One is to register as LLP, for which some investments needs to be done definitely and the profit/losses should be shown. And the other is to have a partnership notary agreements between us. Kindly let us know what is the best option on this.
