DJ for a 40th birthday party

Throwing a 40th and need a DJ who can read a room — a mix of 90s/2000s and a bit of current stuff, keeping a crowd of around 60 on the floor from 8pm till late. You’d bring your own gear and a couple of speakers for a hall. Budget’s about $600 for the night. Let me know your setup, how you take requests, and whether the date’s free.
