Website Product Flow Design Needed

I need the complete user journey for my product section visualised as clear, clickable flows. Our brand guidelines are already established, so every element—from colours and typography to tone—must align with those standards.

The map has to cover the full sequence of:
• Sign-up / Login
• Checkout / Purchase
• User Feedback & Reviews

High-fidelity wireflows created in Figma, Sketch or Adobe XD are ideal, but I’m open to whichever tool you prefer as long as the files are editable and easy for my dev team to reference.

Deliverables
1. Screen-by-screen flow diagrams for each action listed above, including alternate paths and edge cases.
2. Annotations explaining decisions, states, and required components.
3. A hand-off package (source files + PDF export) ready for developers.

Acceptance criteria
• Matches existing brand style exactly.
• All primary and secondary user paths are represented without gaps.
• Files are organised, labeled, and layered logically.

Let me know your timeframe and a fixed price for the full set so we can get started right away.
