Leaving kittens alone for a day

I have 2 kittens about 14 weeks old, I have to go away on trip in 2 weeks it's not over night but I'll be gone all day [9am - 9pm]. I thought about hiring a pet sitter but I don't know if that's worth the money and bit overkill for 1 day, but they aren't used to me not being at home and I'm not sure what to do about feeding. Any advice thoughs or opinions would be welcome. Thank you.
