Whether $5 is good or not, depends entirely on how long it takes ~ including the report. Since you said it takes less than 15 minutes all told, that sounds pretty danged good.
Now if I wasn't such a nervous phone person, and could find phone shops like that. The only phone shops I seem to get emails for are really long/involved ones, or ones with subject matter that is entirely distasteful to me. And none of them pay that well ~ as well as $5 for a quarter hour ~ for the time involved. :/
