This is a UML model of the relationships between potential customers and service providers. The idea is to register both requirements and services provided.
The service site is aimed at B2B and B2C relationships. The model could be applied to any market in theory, but then customised vertically. The working model is the artisans business model (in Brittany) where the business problem is about getting materials at the best price.
The market place receives standard supplier offerings and autoregualtes pricing through reverse auction bids. Users can upload materials requirements.
This model is part of an overall approach to projects, which is “try and model and see if it flies”. If you can’t model it, you can’t build it. However, the inverse is not necessarily true. It’s not because you can model it, that you can create it. Building takes resources, a business case, funding, skills and time.

The concept of a service site
A lot of work is needed to move the model forward from a conceptual one to a live system. The concept has already in use but there continue to be opportunities available.
To which market to apply the concept of a marketplace for services – a site bringing service providers and customers in contact could apply to many markets.
Potential markets for a service site
The concept could be used for the direct sale of farm goods by producers or as an online catalogue between automotive parts producers and buyers, artisans and building materials suppliers, or international estate agents.
One idea was for artisans in the building trade and suppliers of materials, another is for Bio House Building materials.
Amazon marketplace, Cdiscount marché, RDC marketplace, or even Ebay and Price Minister have all implemented market places for products. Eazylang and TM-Town have established translation segments market places.
On the one hand potential customers register a need, and are matched with a provider. Both pay to register and pay when their need is fulfilled
The system is a market maker because you can evaluate the demand and the supply
