On which stage should I form a company for a new business in the UAE?

Hi,

I am planning to start a business consultancy company in the UAE which will manage and run the complete business. We have our own projects in the paper for which we require partners.

At the same time, we are inviting individuals to show their interest to be part of any project as they will inform us their financial capability and once we will have sufficient number of people then we will form a separate LLC company in which all the investors will be the partners and our company will be the consultant to them.

If I want to do this by sending one video to my contacts on social media... is it fine and legal? Should I form the company first before sending the video presentation of the concept... as we are not taking any money from anyone... just to analyze the response of the people?

Thanks.
