A comment of caution: All that glitters is not gold. I accepted and completed a video assignment to travel 268 mls. round for a cleaning. My pay was to be $250+ the charges were waived by presenting a form. What I failed to consider was that with a bright light shining on me and a dentist inches from my chest, my wiring would be noticed. The dentist reported what she saw and my fee was cut in half. In that I could have had the service through Groupon in my hometown for an average of $50, my pay for a five hour drive @ $.30 a mile computes to a net of $19 an hour, which would have been much worse had the 1/2 fee not been paid.
If I were to attempt another such shop, it would definitely not require any distant travel nor the advancement of a dime.
