discount for regular visits?

My friend told me about the site/app and said it cost $10/visit...well, no, everyone I saw locally was more like $15. But, if I need someone to come every weekday at lunchtime is there any sort of discount, like $10/day for 5 days or $50/wk?

I'm trying to find an affordable solution to my new pup and her soon to be adopted brother or sister but I just need someone to take only like 10 minutes (enough time to at least pee) total for the two of them in my fenced-in backyard. I don't think they need the advertised 30 minutes.

I'm not looking for offers, just an answer or suggestions to get the ongoing cost lowered somehow. My current idea is to actually start making friends with neighbors (perish the thought, right? :D ) to see if I can talk a local kid into doing it. I'd rather have a pro though.
