This question can best be answered by you yourself! Each category and each location has it’s own supply and demand. In fact, some categories are highly seasonal and their demand changes throughout the year. UrbanPro.com can help showcase your profile, but the number of leads that are generated greatly depend upon your category, your location, your Pro Score etc. Therefore, it becomes doubly important that you maintain a high Pro Score to differentiate yourself to the student.
Also, participate in as many Question and Answers sessions as possible to create a good reputation among students seeking answers.
Remember, there is no upper limit on the number of leads you can get in a month!
