Curious on rates for mixing a single.

I’d like some help with some house music I’m making. I’ve been producing music for over 20 years, but I still can’t get my stuff to sound quite right, at least in this genre. I’m wondering if hiring someone like yourself might help me get there. I’ve never outsourced before. So if things go well and I can afford your rates, I could see myself doing it again. What would you charge for a single? Current project is certaindaze, you can hear my stuff on streaming platforms. Any information about your services or thoughts on how I can improve would be very much appreciated! Thanks for your time, Greg
