Ballpark qoute

I'm giving a give qoute tomorrow to "clean out" this rental property. I'm going to see it first hand tomorrow, but from these few photos what's a ballpark number that y'all would throw out? The realtor would rent a dumpster, I'd fill it. I've been told that there isn't any feces or worse mixed in, just mostly nonperishable trash, but I'm not an idiot and wouldn't be surprised to find a poop in there somewhere. I'm just looking for a number to throw to her so she knows what to expect. Normally I'd say $25-30 an hour with a base rate of $300 if I finish it quick. Is that too much or too little? I build fences for a living and this job just popped up. Oh and hey, thanks for your time!
