Anyone want to trade?

Problem

each of us has things that throw a pity, but it should. However, we understand that it is unlikely someone will agree to pay for these things at least some money. On the other hand, we often need to buy things that don't necessarily have to be new, and for which I don't really want to pay. The classic solution is to advertise on the exchange. Resorting to this decision we are faced with the fact that even in the big cities is not so many people who have what you need and who need what you have.

the Idea for a startup

Bulletin Board. Ads are of two types:

the
• I Have
the
• I need

the User accesses the contact data of other users only when placed at least one ad of each type. This is important. Once it is done, the system begins to build a chain of (one or more alternatives,) metabolism, which would satisfy the following conditions:

the
1. At the ends of the chain should be participants who have what you need and who needs what you have

the Chain has to be of minimum length the

2. All participants in the chain must be within reach of each other (in the same city, area)

Where the money is?

monetization Options:

the
1. Advertising (brilliant, right?)
the
2. Premium accounts (members with a premium account are included in the chain in the first place)
the
3. services of the financial guarantor
the
4. the services of a facilitator of exchange

directions of the development of ideas

the
• Company in the chain
the
• not only "clean" traffic, but with a surcharge and also exchange a few things of one or more
the
• Search not only what is clearly necessary, but that in principle can be useful. Fuzzy search conditions

Problem

the
• Inconvenient to arrange meetings of a chain of more than 4 members

Many visitors will be just too lazy to log information about what is available and what you need the

• non-Trivial (and therefore probably expensive to implement and maintain) a search algorithm chains

realizing the strength of his team, but the enthusiasm will not last long, and the project is not fast. So make the idea public.
