Unfortunately FFF it does take time to build up a decent body of your own students. Instructors who've been there longer will get more flying simply because they are more of a known quantity than you are currently.
Give it a few weeks and make sure you do the weekends and lots of trial lessons. This is where you'll meet the majority of prospective PPL students and once they've flown with you thet'll be loath to move to others. (Not blowing sunshine up your a*se, student loyalty can be a strange thing!)
Where are you teaching?
Good luck, don't get too despondant it will pick up pretty soon. Be optimistic and friendly to all who come into the club. Most of all however, be available and you will get more students than you can handle soon enough!
