A schedule-based, neighborhood-based electronic marketplace for services is presented here. The electronic marketplace allows users to make use of their time, such as their spare time, to offer, sell, or trade services to other users in their selected neighborhoods. Users can also search the electronic marketplace to buy or trade services in their selected neighborhoods. In addition, users other than individuals, such as companies, can use all services offered by the electronic market place. One way to mark neighborhoods for the electronic market place is the use of postal zip codes. This includes registration, search, advertising, e-commerce, user-ranking, and user-interaction. It contains user profile, necessary database, password, and other necessary information, such as usage of encryption, watermarking, DRM, PKI, RFID, or biometrics. It contains a search engine to allow looking for specific services in selected time and locations. It allows users to advertise their service offerings in selected neighborhoods at selected time. It contains scheduling, job category, and service pricing information. It allows commission-based transactions in the marketplace (or referral fees/finder's fee). It also allows service to trade between users. It allows service providers and receivers to rank each other based on the desired factors. It allows interaction of users electronically.
