Remote Data Collection and Instrument Control

I am working on an application using an instrument that makes a measurement
every 10 minutes and provides the output in the form of a 4-20 ma signal.
(the measurement value is held until updated 10 minutes later.) We want the
ability to transmit this data to a central site using some kind of wireless
communication. Are there any off the shelf systems available designed to
accomplish that as opposed to me trying to integrate the various wireless
and A/D conversion components? I realize distance is a critical factor so
assume in one case we're talking up to 1000' and in another case, several
miles, both situations outdoors. It would also be nice if we could
potentially transmit data from sensors detecting temperature and wind
parameters and possibly control of devices in the remote station. Any good
unbiased websites where an engineer like me who is not expert in digital and
wireless technology could get up to speed in this area? TIA.
