Attendance Monitoring System

Hello. I need three pieces of a device to monitor the attandance of the employees. So the functionality must be: 1. Device must be able to read the fingerprint. 2. Device must be able to send the code of the fingerprint to the remote WEB server using GPRS (GSM). 3. Device must be able to receive the code from WEB server as a ACCEPT or DENY - to indicate if the check in/out is successful (green and red led). 4. Device must be able to work of the 230V, 50Hz (can use the adapter). 5. Device must be able to be wall mounted. I need a real devices - the freelancer must do the programming, find the best (price also matters) parts for the devices and test it.
