Here is my take on referrals--for what it is worth . . .
1) Schedulers always want you to send them more bodies but most shoppers who are serious or semi-serious have already registered with the company so what is the point?
2) I don't know you from Adam (or Eve as the case may be) and I would be unwilling to have you use me as your referral for a job because if you screw up or flake it will reflect on me. I have tried to get together shoppers and companies in the past where over time I had gotten to know the shopper and the company and have thought they would be a good fit, but I have never done it for a referral fee. Rather if it works out, the company will be pleased with me and so will the shopper, which brings more opportunities to me rather than a measly $5 or whatever the referral fee is these days.
3) Generally if a scheduler or company wants a reliable shopper in Peoria or wherever, they have communicated with me personally to see if I know someone because of their needs. These random "Refer someone and get $X" I personally find noxious.
Specifically with BWW, it is shopped by a number of different companies. There are some of the shops that are completely not worthwhile, there are some that are okay. Certainly soliciting shoppers in a thread about BWW for any of the companies that perform the shops would be an ICA agreement violation as well as a violation of the rules of this forum.
