Advice needed on steel prepping prior to painting

I've had an address sign made for my house from 1/4" steel plate, with the numbers laser cut out. I want to coat the sign with a commercial grade epoxy coating that I have, and want advice on prepping the surface. The steel is new and is not appreciably rusty, but it has that dark-brownish, oxidized surface appearance. I previously used this epoxy coating on a large steel structure that was sandblasted first before it was primed. But I don't have a sandblasting setup of my own, and I can't find anyone to do this small job at a reasonable price. What are my next best options for cleaning it up before I coat it?
