A little stuck - who should I be hiring?

I am looking for someone who can help me rewrite things.

I have my product (website) and I am slowly starting all my social media campaigns but I suck at the wording/what to write - how to get viewers attention. I word things wrong and can never come up with something catchy and witty. Would love to hire someone to help me write some really banging one or two liners and a paragraph or two.

I am not sure what I should search for on here. I have looked up Press Release, campaign, marketers but it is hard to find something specific.

Any direction would be awesome thankyou so muchhhhhh!!!!
