Handyman Job in Los Angeles, California

My wife and I just moved into our new photography studio in downtown Los Angeles (arts district). Its a brick and concrete loft. We are looking for installations on walls and in the ceiling. Need a handyman experienced with installing into concrete ceiling and walls. We are looking to do install lighting fixtures, also installing a rail pipe system into the ceiling to hang our professional photography strobes from. I can share photos of exactly what we are looking to get done. We would like to get this done asap.
