When you going to launcj full version of platform? Now this looks like for just a simple movie poster. And we cant estimate this. And how much will be cost acces to your platform?
I think the ICO is meant to deliver the things you are asking for, although the costs can be shared already of course
For a full-fledged launch of the platform I think it will take a lot of time, the design of the site and its contents is one thing, but for agreed with the film companies it can take a lot of time to conclude licensing.
