Licensed plumber for water filtration installs (1099, steady work)

I own Seattle Water Filtration, a local company installing whole-home carbon filters and under-sink RO systems across the South Sound and Seattle area (about 25 miles around Federal Way).
Looking for a licensed WA plumber to take installs on a per-job basis.
What you get:

• Paid $400+ per install, paid within 7 days of completion
• Same two systems every time, so jobs are predictable (about 4 hours each)
• Equipment is supplied. You bring tools and skills.
• We handle sales, scheduling and customer service. You just show up and install.
• Steady volume. We're booking 3-5 installs a week and growing.

What I need:

• Active WA plumbing license, bonded and insured
• Reliable truck and tools
• You show up on time, communicate and clean up after the job
• Softener or RO experience is a plus, not required

Email me with your license number and service area. Happy to jump on a quick call.
