Any Rockland County, NY peeps? Transport to LGA recommendations

[DisneyBelle27]

So I figured it wouldn't hurt to throw this out there. I live in Rockland County, NY and am just looking for transportation recommendations to get to LaGuardia Airport next week. We only need it one-way as I have family to pick us up on return. We don't need anything fancy, just clean and reliable, and hopefully not costing an arm and a leg plus a first-born child, lol. I know it's kind of a geographically-specific question, but on the off-chance there's anyone else here from this area any advice/recommendations are appreciated!

Thanks!
