The main idea is to develop/clone a city guide app with a UI similar to "Triposo". You may find "Triposo" here: http://www.triposo.com/

Thus, the main features will be:

1) All content (map, POIs, text, photos, etc) available offline, with automatic online updates when available.
2) Using Openstreetmap data for the map.
3) Possibility to use a main app where the user can download and add separate cities, but also use a stand-alone city app (just like “Triposo”).
4) Android and i-OS platforms.
5) Dual language selection (English/ Greek)
6) UI similar to "Triposo" - we may discuss some slight differences when we begin our co-operation.
7) Apart from the usual POI categories (accommodation, sightseeing, restaurants, etc) have a special POI category for a business listing.
8) A relatively small file size in the range of 2-5MB.

As owners of this app we would like to be able to:

1) Edit the POIs by importing popular file formats (shp, xml, csv, etc)
2) Edit the content (POIs, text, photos) for possible online updates.
3) Possibly initiate a map update if there's newer data in Openstreetmap. (Not very important but we would like to see if this is possible)

We're currently thinking of starting off with one city, but if the end product is satisfactory and within our goals, we would love to co-operate further with you on a project-per-city basis. Thus, we would like to have a price quote per city in the future, keeping in mind that you'll be basically using the same code.

We'll be expecting a bid for the features described above, or for any varieties you may have in mind (single platform, deviation from the initial specs depending on your needs, etc). Do not hesitate to contact again, should you require any further info.
