Such projects are a fairly new phenomenon in the RuNet; they are essentially a virtual exchange or a platform for organizing meetings between customers and service providers. At their core, these services enable customers of a wide variety of work to find a contractor, and contractors to find those who may need their services. At the moment, for example, 16 areas are already operating on the YouDo platform, which have developed according to the specifics of the services provided, and 2 million participants who create and complete about 4,000 tasks daily.
Since not all offers and orders can be accommodated within the already established framework, the creation of such web services continues to remain relevant, especially if we take into account that the scope of the already operating popular web services is only the cities of Moscow and St. Petersburg. For other Russian regions, such projects are essentially an unplowed field where you can earn money by charging customers or contractors a percentage for using a publicly accessible platform.
The idea of creating analogues of YouDo.com or Freelance.ru is, on the one hand, simple, but on the other hand, it requires working out many details that will depend on each specific customer who wants to have such an exchange under their control. Such details include methods of registration and verification of participants, schemes for placing orders and service offers, a system for calculating the rating of participants, the possibility of making cash and non-cash payments, a scheme for collecting interest, etc. A ready-made and debugged service will require a one-time investment of funds in order to subsequently bring only income.
