Pet Sitter in Modesto, California

I am 16 years old and am currently a junior at Joseph A Gregori high school in Modesto Ca. I am not able to attain a full time/part time job due to after school sports activities and lack of time so i am looking for small jobs that i can do to earn money for a car. I currently have a license. I have experience in babysitting (ages 1 and above), i have house sat multiple times for family friends for 3 days, i have also pet sat dogs and cats. I am a very reliable and responsible student with a 3.2 gpa and i can easily get recommendations.
