You should hire an experiential agency that makes the most sense for you to work with.
It could be big agency.
It could be a small agency.
It really depends upon what type of services you’re looking for, what kind of partnership you’re looking for, if you’re looking for a full-service agency, or somebody that just does something like niche marketing.
So it really just depends on your goals and objectives of what you’re looking for in an agency.
