Since I last posted about this, we have not heard anything further from this man (except receiving this check)
This is taken from Care.com in reference to scams...
There are two main types of scams that are prevalent on the Internet: the “overpayment scam” and the “pay in advance scam.” They're very similar and usually go something like this...
A scammer poses as an employer and attempts to trick you into sending money. Typically, the employer reaches out via text message with a job offer that seems too good to be true.
Once you reply, the scammer may ask you to buy a needed item (like a toy or wheelchair) or claim they're relocating and want to pay you in advance.
After you share your full name and address, the scammer sends you a check (often for a large sum of money) and requests that you cash it and wire a portion of the money back to them. They may tell you to keep the rest.
But here's where the scam comes in: the check is fake. Unfortunately, you often don't learn that until it’s too late -- after you've already sent a portion of the money back to the scammer, which you're then responsible for repaying to the bank, as well as additional fees associated with this type of fraud. In some cases this can amount to thousands of dollars of lost funds.
