I don't think it'd be very effective. Running the marketing and seeing what works is a critical feedback loop for finding product market fit. Someone who can do that on your behalf is probably expensive. You could probably find somebody to do social media or whatever for you, but there's no guarantee that's the most effective channel and, again, if you don't have product market fit you'd be shoveling money into a firepit.
