Hello @Middi57 and a very warm welcome to the Community Forum 
I would suggest that you add your TrustedHousesitters profile on to your Forum profile by following the attached link. This will then enable others on here to offer you helpful advice and feedback and will also give your listing extra exposure!
If you are unsure how to do this, or if you have any questions at all, do not hesitate to ask, we are all more than happy to help.
If you have only just put your listing on, you would need to give it some more time, people will perhaps be looking at whether your sit is feasible for them before they apply. There are some single sitters that would be happy with this number of pets so I would certainly not restrict your application pool and sitters travel many miles or a few miles to sit, everybody’s situation is different as is the location they choose.
Also, remember you can use the spyglass symbol at the top of the page next to the TrustedHousesitters logo and search for any questions that you may have as they have most likely already been answered on here and of course if not then please just ask!
