I'd take a UI-first approach and then figure out what and how much could be implemented. It should be a complete profile page. 1 page with different sections. 1st section: Default Nostr profile infos 2nd section: A bit more info about business type, services offered etc. 3rd section: Skills and expertise. Maybe as tags for the beginning 4th section: Portfolio, lates work examples with screenshots/photos, title, description 5th section: Recommendations, Testimonials from other nostriches 6th or sidebar section: A hire/contact form and a zap button somewhere
