Production of a 5-minute advertising clip (pricing for future project)

Good day, I wanted to inquire about an estimate for an assignment (which may come to us in mid-November). At this point, we do not know the details from the potential client, so please give us an estimate (the top of the estimate range) so that we can calculate the design costs and choose the person we will work with if we receive the order from the client.

The subject will be to make an advertising clip (min. 5 minutes) presenting the services and website (with a store) of a client selling photovoltaic panels.

The video should include animations, photos of the client's products, footage from the website (no footage of people or team).

Materials in the form of photos and graphics from the website will be provided.

I realize that there is not much detail here at this point, but I would ask you to give an upper estimate range for such an assignment.
