8 days, 2 cats - How much should I pay my sitter?

Me (student, employed part-time) and my gf (employed full-time) need cat-sitting for 8 days. We have 2 adult cats with no health issues or behavioral issues. 2 litter boxes total. The sitter would just need to stop by once per day for a litter scoop, food and water refresh, and some cuddles and play. What's a reasonable per day pay for Brooklyn, NY?
