Your first three steps

  2. Build a small showroom set-up or demo kit and a portfolio of example projects with photos
  3. Create a standard quote template and terms covering equipment, installation and after-install support
Who pays

Homeowners doing renovations, self-builders, small developers and interior designers.

How it makes money

Project quotes covering design, equipment and installation, with optional paid support or maintenance visits afterwards.

Skills that help
