Demonstrator program for arduino with wiznet to communicate via tcpip with a web based database template ( your solution). Both programs need to be modular and well documented in a template manner to enable easy addition of extra elements. Communications will require a user ID, API KEY, project ID, object ID.
For this initial project I require 2 sensors and one control (connected to A1,A2 and A3 respectively on the arduiono and communicating to Parameters flow, temperature and swirch1 in the database.). Switch1 in the database must update the output of a3 on the arduino on change. The sensor readings should update every minute.
Note that I don't require any hardware development but I would prefer it if you develop and test the Arduino program on an actual Arduino with a wiznet interface. As part of the project I am willing to have shipped an Iteadstudio Iboard which incorporates the wiznet onboard.
The Arduino code would not be that dissimilar to the those examples provided with pachube/cosm/xively.
Please feel free to quote what you think this project is worth, I am prepared to pay for the right person but I would prefer to limit the terms of this initial stage (or change to an hourly rate) rather than award a larger project upfront.
