Hi I just signed up to be a SS, but I have some questions about compensation & reimbursements?

How does that work? Do I need money to do a task? Does SS pay for meals or whatever the task is, or do I have to come out of pocket?

I am pregnant trying to make some extra money on the side since we are a 1 income family!

Also if there is anything else else I need to know please let me know!

Thanks in advance!
