I LOVE Trendsource, they provide me with a lot of work.
PAD - stands for Pre-Authorized Distance aka a travel bonus. Since nearly every job that comes up is over 20 mi from me I always request the job with PAD (I base it loosely on 1.00 a mi. one way). I don't always get the job because someone else is willing to do it for no PAD or less. That is the challenge, getting jobs that are so far out that nobody else will do them and the PAD is acceptable.
If you are in a metro area you will need to click on those jobs within seconds sometimes or lose out.
PS - There are many different types of audits - most require making an appt. to meet at the business. They are not hard but are more time consuming / limiting than just doing a property inspection where you don't go on to the property, just take pics from afar.
Pics are THE most important thing - make sure you get good at not cropping out the edges of buildings.
