I have self assign of 4 on I secret shop. A suggestion to help with prophet companies is to click on show me visits I can accept and then search for visits outside my area. Click on cities close by or ones you are willing to do after selecting your state from the drop down. Many times the city your in shows up with shops even though it don't show up at first. The good news is all shops shown on prophet are self assign with no limit.
Shopping Western NY, Northeast and Central PA, and parts of Ohio and West Virginia. Have car will travel anywhere if the monies right.
