Data collection server over IP

I want to collect data from several devices which are contacting the central server every hour over IP (mobile via GPRS). There is not much data and needs to be recorded in a central database. Doing something with the data is a project that will be looked at after this. It is now just collecting, but in phase 2 we also need to send parameters back to the devic to change settings (change time to call in, change server address etc) I am thinking of: - windows based web server - collecting data with a service - adding data to a MYSQL database - audit file (.txt/.csv) with logging of all communication When you are interested in this small project, please tell me: - in what language you propose to make this - how long it will take - what you will do differently than I propose above - how long you think it will take. there is no immediate hurry. I am fine if it takes 3-4 weeks in leadtime. Good documentation/well written code and a good price is more important. (Use this as filler of 'time left in between projects') .
