Anyone know where I could find a freelance copywriter - I never have any luck with Fiverr.

I belong to a closed copywriting FB group. I you message me with details, I might be able to put you in touch with some talent.

If you are willing to spend the time, effort and money for a freelancer, definitely lookup upwork.com or freelancer.com Alternatively, do a quick search on FB groups. If you need work on a consistent basis, hire those agencies that offer 'unlimited copywriting' on a monthly basis. They can usually churn out 3-5 articles a month. Scribly is the first that comes to my mind but you can do a quick Google on 'unlimited copywriting' Cheers!
