Pet Sitter Needed

I have a 6lb non-reactive chihuahua. I will need someone to let her into the backyard once a day around 10-10:30 a.m. to use the bathroom; usually she only wants to be outside for 5-10 minutes. I work full-time and am too far away to let her out myself, unfortunately. Whole process takes me a maximum of 15 minutes, usually-- I just pick her up off the couch where she's napping, set her on the grass, watch her use the bathroom, and either she'll run back to the door herself or once she's used the bathroom I'll pick her up and carry her inside and set her back on the couch.
