How to judge fit before requesting a proposal

A good fit has a clear decision maker, a defined audience or workflow, and someone who can provide content and review milestones. You only need to share the problem, required pages or actions, available material, budget range, and preferred launch window—not a technical specification.

Four-stage project process

Discovery and scope

Confirm goals, limits, responsibilities, and the proposal.

Planning and content structure

Organize pages, flows, content, and delivery stages.

Development and review

Build, test, and review each agreed stage.

Launch and warranty

Deploy, hand over, and provide a 30-day defect warranty.

What happens after you make contact

Send the service type, budget, timeline, and a short description of what exists and what should change. I will check fit and missing dependencies, then suggest a focused discovery call or clearly explain when the request needs more definition or another specialist.
