How can I make a p2p currency exchange between people?

Question

CMS

Tell me, is there a ready-made or semi-finished solution for a currency exchange exchange between people?
Like localbitcoins or p2p.Webmoney but without being tied to any currency, i.e., for example:
A person needs to exchange bucks for rubles / hryvnia / rupees / Webmoney, etc., he can:
1. select by filters in the search and find already existing offers for the reverse exchange and location (city, district), if cash. And press the button - offer an exchange.
2. Create your offer.
In principle, while it is possible to consider in the format of announcements at the initial stage, with further refinement.
Also:
3. A rating and feedback system is desirable.
4.LS system
5. As an option, later fasten ads for the purchase and sale of goods, such as Avito. But for now, currency exchange is an urgent issue.
The site itself DOES NOT PARTICIPATE in the exchange, it just allows people to find each other!
While the task and relevance of the site is aimed at local groups of people, you can even say for "their own", I'm not pursuing any scale yet, but in the future, it's possible)
