Pay & Benefits

Compensation Structure – Commission‑Based Pay Plan

This position offers a commission‑based pay plan, giving you the opportunity to directly control your earnings. Under this structure, you will earn 30% of the total labor dollars you bill each month.

How it Works (Example):

  • If you bill $30,000 in labor in a given month
  • Your pay for that month will be 30% of that amount
  • $30,000 × 30% = $9,000 in earnings

This pay plan rewards productivity, efficiency, and high‑quality work. The more labor you bill, the more you earn—there is no cap on your monthly income potential.

  • Competitive pay: estimated $50,000 – $250,000+ annually

  • Paid Vacation & Holidays

  • Medical, Dental & Vision Insurance

  • 401(k) with Company Match (after 1 year)
