Hi Sally - Sorry you lost your agency but, yes, you have to keep enough in your agency for the rent to be paid.
As for the Marwadi Pagdi's, which I assume is what you were trying to say, they are easy to come by, so, should you start another agency, don't worry about not being able to get more. Those are easy items to get :)
Maybe you should save up alot of money first before starting an agency, if you arent here all the time so, the agency can stay up while you are away or....wait until you can be on Sleuth more before opening one. It becomes a waste of money if you open one, then it shuts down, after you being gone for awhile.
Good luck :)
