First experience in Europe

Guys do you think it would be realistic for me to get my first experience in the next 3 months by applying to be a sitter? I'm new to this, and I discovered this site very recently.

I'd be in Europe and have the flexibility to work in different countries around me, and as I can work from anywhere, it would be an advantage to save money on my stay and get to know a new country/city.

I have a lot of experience with dogs and cats, especially with medication, as I had a sick cat that needed daily injections and special care with feeding.
Btw any tips on how to make my profile or first message more attractive in order to get my first experience would be very welcome :)
