Hi @JennyM and welcome. As always, @anon36831737 gives great suggestions.
If you have already joined TrustedHousesitters, I would suggest you provide details of your listing, by posting the location (city/country as shown in listing) and date range. This way sitters can easily find your listing. You can also embed your listing in your forum username.
If you have not yet joined THS, I’ll add a link to show the various membership levels and benefits.
