Digital platform development

Description

I'm looking for an ambitious web developer to create a website (and then down the line integrate an app for Android & iPhone or we can hire someone to do this).
The philosophy is to build a minimum model and based on customer feedback, quickly develop and test whether there is a business. Users register and create their bio.
Ultimately, we'd build the product and then turn it around and sell it.
Home page:Registration formList of the latest bios
User functionality:example.com/theirusername (free) or Custom domain, sub domain and personalised link (paid)biographydisplay photoPersonalised link (free) or multiple links (paid)Predetermined social media links facebook, x, linkedin etc.Cover photo and header imagelocatione-mail addressPhone numberVisitor traffic analytics and how many clicks a link has hadPayment facility Username login detailsPost to their page Users can follow each other.

Let me know how much this would cost to build. Any AI responses will be declined. I'm sick of receiving AI responses to my jobs. Please stop.
