Happy to share. I will say that I've been working with MF since 2009, and EVERY time a scheduler called me, I got their name and phone number. I have a list now of about 40 schedulers with them. When I see a shop I want, I start going down the list and leaving phone messages.
One thing to know, if you've done a shop for them for $5, you're "locked" into that $5. I made that mistake early on, thinking I was "paying my dues", getting my foot in the door, building a record with them as a reliable shopper, all that. I also learned that if you don't do that shop for months and months and months, your "pay history" for that shop eventually falls off. Then you're free to shoot for the moon.
And be really, really nice to the schedulers! After a few phone conversations, I feel comfortable asking "how's your mom doing?", "how are your courses going this semester?" "how's your boy doing?".
Even the ones in the Philippines (can't spell it, LOL!) have their own stories...did you know they earn $6-10 A DAY? So when they offer an additional $2 to do a shop, to them that's a great deal of money? The government mandated minimum wage there for non-agricultural workers is about $5 a day, so the ones who work for MF call center consider themselves very, very lucky. It is incomprehensible to them that we have to have $80 for a shop that's 100 miles away. The reimbursement for a FF meal for MF is like a whole day's pay for one of those call center employees.
Good luck.
