Part 1:

PI entered into a contract to paint the exterior and the first-floor interior of a large home belonging to the Jacksons. When the work was completed, PI billed the Jacksons for $4500 for the total cost of the work performed. After 90 days, PI re-sent the bill, but after 120 days the Jacksons still had not paid.

Evaluate and describe what remedies are available to PI to collect the unpaid bill?
