My name is vishal from amritsar punjab i just want to make an aap for realestate E-brokers where each broker gonna have their profile and the mentioned area where and what part of city or country they dealing in, and have direct customers. Note : only brokers allowed who are having direct customers no thrid parties is allowed and by the permission of broker he/she can share thier properties with other e-brokers or real estate agencies for their deal where ever and whenever they want . Im gonna charge less than 1 dollar for joining , it should be for worldwide community no barries for realestate deals whole process gonna be online so can earn by taffic on my aap easy to search there should be also an page for listing by brokers to cutomer and much more have this brilliant idea in my mind from a long time because im handling realestate business from 1 year my father owned this business from last 13 year and now i want to make it online through aap only for realestate brokers
