Seeking occasional weekend afternoon sitter for 5 y/o autistic boy

We're looking for a sitter to help watch our 5 y/o autistic boy on the weekends. Typically about 3-4 hours one weekend afternoon a week, or every 2 weeks. Duties required would be playing with him at home, or can take him around the neighborhood to bike/walk/go to the local playground (2 blocks away). He's potty trained but needs some assistance in the bathroom with wiping. Not aggressive, has a good sense of danger/is cautious, sometimes has sensory/anxiety issues where co-regulating is important to help him calm down. To show me that you've read this posting can you note your special needs experience when messaging? Thank you!
