Can you? Yes. Should you? No.
Many reasons why no, and they were already mentioned on this thread. Mainly, your contractor intends to cheat on his taxes, and you will be helping him. Unless he completes Form W-9 and provides his valid SSN, which he won't, so you won't be able to issue him a 1099. You will probably end up breaking two Federal laws: labor/immigration laws (as he may not be authorized to legally work here) and tax laws.
You're unlikely to be caught, but you might, and then you face various risks of extra taxes, penalties etc.
If you insist on taking this risk, then your best practice for self-protection is to have a simple written and SIGNED contract: you do this, and I pay you this. Then have him acknowledge on the same piece of paper the receipt of the money.
Taxes are not the only reason to have things written and signed. He can later claim that he did not receive this money from you and demand a second payment - either because he is a crook or because he got drunk/high on your money and forgot he got paid (ask me how I know). He can even try to place a lien against you.
Think about it this way. He ain't scared of the IRS. Would he be scared of you?
If he accepts Zelle or PayPal or check - you're better protected, but he probably won't.
