What to send

  • Named options or a bounded set to shortlist
  • Budget, must-haves, priorities and non-negotiables
  • What you already know, and what decision follows

Start by describing the materials you already have; missing details can be added when we agree the scope. Before work begins, we will confirm the materials, permissions and working conditions needed for your specific task.

Possible outputs

  • Comparison matrix with documented criteria
  • Recommended trade-offs and counterarguments
  • Follow-up questions or checks before committing

Key check

Show which hard constraints pass and what is unknown.

Start with a short note

Three answers are enough. I will reply with what else is needed and whether a diagnosis comes first. You get a quote before any work starts.
