MVP Developer Needed for Automated Influencer/Brand Platform (No-Code: Bubble or FlutterFlow)

I am a non-technical founder looking to build a Minimum Viable Product (MVP) for a web application that connects YouTube creators with brand sponsors. The goal of this platform is to automate the contract, script compliance, and payment process for video sponsorships. I want to build this efficiently using visual No-Code platforms like Bubble or FlutterFlow to keep development quick and scalable. Key Features Required in the MVP: 1. User Onboarding: Secure login for YouTubers (via YouTube API to pull subscriber/view data) and a separate login portal for Brands. 2. Automated Pricing & Matching: A simple database system that suggests matching creators to brands based on target demographics and applies a fixed math formula to calculate video pricing. 3. AI Script Compliance: Integration with a basic AI text tool (like OpenAI API) to scan uploaded video transcripts to ensure specific sponsor talking points are present. 4. Escrow Payment Milestone: A basic visual dashboard showing funds held securely, releasing a 90% payout to the creator and a 10% commission to the platform administration upon video approval. What I Need From You: - A rough estimate of the hours and cost required to build this prototype. - Recommendations on whether Bubble or FlutterFlow is better for this logic. - Examples of previous No-Code platforms or marketplace dashboards you have built.
