They pay as promised, not high pay. Emails to them are often ignored. The owner can be rude.

I have done a few assignments for SC this month. My emails are always answered, usually on the same day. One time I had a question about the location of a shop that had to be done that day. I emailed my schedular my cell phone number, and he called within 10-15 minutes.
