Greetings,
your project's description sounds exciting. I will gladly start working with you right now, even before you officially hire me. Moreover, before the start, and in order to showcase my work, I'm willing to craft a few pages sample drafts, free of charge. First estimate is that it will require up to 25 days depending on the amount of content and specific preferences about the design, user experience, animations and user interactions.
Feel free to contact me anytime.
Cheers, Drago
