Handheld Device Prototyping and Manufacture

RFQ Description

I am interested in creating a simple handheld device and would like your help in the prototyping and/or manufacturing stages. I am new to electronics manufacturing so I apologize in advance if any of my questions seem a bit rookie. The device I want to build is intended to be used for viewing checklists (shopping lists, to-do lists, etc.). I am prepared to create an entirely new product, but I would also be willing to repurpose an existing devise if it closely resembles the specifications Im looking for. If you think you may be able to help me, please read on.Battery: preferably internal and charged through the mini USB port; however, I would also like to be quoted on the same unit with external batteriesConnector: USB Type A Male to Type Mini B 5-pin Male (MD Type). The mini USB port would be on the side of the deviceMemory: very little required as the firmware will only handle basic list and calendar files. [Please advise if you have suggestions]Screen: black and white; high contrast so that it will be visible in sunlight. [Please advise if you have any suggestions] Interface: 4 buttons, one on the right side panel of the unit and the other three on the left side Firmware: will need to interface with PC software that syncs lists and calendar items; will need to display lists, calendar, date and time[Please advise if you have any suggestions]Software: I have this laid out in another document; please advise if your company does this otherwise I will contract an independent developerOther considerations: Im looking for a per unit cost of roughly Ask Buyer US or less on an order of 500 to 1000 units. Suggestions to lower the manufacturing costs are encouraged. If your company can help with the prototyping, please also provide some rough estimates of these costs. handheld, mobile, computer handheld devices, mobile computers
