Got it! Here's a way you could phrase that: Hi there! I'm an experienced pet sitter with several years of hands-on experience in the U.S. I've recently moved here for school, and as a full-time student with a flexible schedule, I have plenty of availability to care for your pets. Whether you need someone to drop by for a walk, feed them, or just keep them company, I can easily accommodate your needs. Let me know how I can help!
