development of a swimming pool

Looking for a product developer for the swimming pool business to develop a product to measure pH/temp/chlorine for private swimming pools. A similar system exists already on the market, but we want our own product. Competitor product: [login to view URL] I had a former developer doing a lot of this job already, so the device is now working: - sensors are reading - a display is working - pumps are running Unfortunately, the developer disappeared so I need to find somebody who can continue his work. What is left for the project: - Test and correct failures of the device - Update the background for the display - Create web page for uploading the data client/admin - Admin should see all the devices and also configure these through the web page - Client can only see his own device - Create an android app / iPhone app - Protect the device from copy and multiply Regards,
