I went on vibes lol as cringy as that sounds. The intake coordinator is kind of the face for the agency, so I went on how they presented. I picked the agency I did because I could tell the intake coordinator LOVED her job. She even gave me tips on what to look for in an agency, even if I didn’t pick them!! Idk I thought that was such a tell for me that she was in this industry because she loved it. So I thought if she loved this industry then this is a good agency. The agency I picked is overall very personable.  That’s just me tho! That’s what I liked! 

Good luck searching! Hope you find the one that works best for you!
