Normally, your contractor will be the one who fills out the form and submits their W-9 forms. This is because this entails confidential information that your contractor alone should know.

You'll just have to make sure to ask for the personal details needed for your contractor. You can follow this article so you'll know how W-9 is added to complete your contractor's 1099: Fill Out A W-9 And View Your 1099-MISC in QuickBooks Self-Employed.
