how long does it typically takes to get your very first client ?

It varies based on many factors: where you're located, demand in the area, how appealing (perceived match/fit) or competitive your profile is compared to others, availability, and more.

At a quick glance of your profile, I saw that your calendar shows you're available only 4 days a week. If I was a pet owner in your neighborhood looking for Boarding services (which is Rover's #1 top needed & booked service) that could eliminate you from consideration because it seems most people who need boarding will want to book their pet for a week or more at a time, especially at this time of year.
