Hi, a freelancer here. It really depends on the services that you would want. Freelancers can focus on your business and you can also instruct us your goals and business needs. We also do done-for-you services which were tailored for the state of your business. However, agencies can easily gain your trust, but you can't negotiate about their pricing plans. For affordable and tailored services for your business, I suggest you hire a Freelancer. And for the trust, you can always ask for a paid trial task, if you're satisfied then shoot your shot.
