Welcome to the forum @sparkinit
A sit with 6 pets will not be attractive to many sitters who ( before reading any further ) will assume that it will be a lot of work and take up a lot of time
I note you say that
If this is true then make that your title to catch the attention . Then be more specific in the responsibilities section about the daily routine and the time it will take for a sitter.

Sitters don’t expect food to be provided but if that is what you are offering to provide all their food for the sit then you should state that . If not then the sentence isn’t relevant .
When we started out we had no external reviews but after video calls 4 homeowners confirmed us as sitters . We have now done 15 sits all 5 star reviews and have been back to sit again for those first 4 owners . Two of them were also new to THS so had no reviews. We all have to start somewhere.
