Walker Needed For 3 Dogs

I have three dogs of varying activity level, all of whom are 9-10 years old. Freckles is a miniature dachshund Lena is a medium sized black dog Luca is a yellow lab I work for a firm and will be getting to the point at which I'm just not able to take them out as often as I would like to at this time. I'm looking for a regular dog walker for tax season and moving forward that would take them out some time in the early-mid afternoon. Luca likes a longer walk (20 min or so is great), but Freckles and Lena really just need to stretch their legs. I usually just take them down the block and back. Thanks!
