Data monitoring, SMS - microcontroller interface, LCD disp

I am looking for a system to acquire data (analog) and send it over SMS.
I need it done with a PIC and a quad band GSM modem.
The idea is to scan 6 analog channels (4 current, 2 voltage) in 8 bit resolution and send the data at specific interval using a SMS. The converted data needs to have a time stamp added to it.
The intervals to scan the data needs to be programmable by receiving the SMS.
The interval to send the SMS also need to be programmable by receiving a SMS.
I also need to store this data in a local I2C flash,in a FIFO, until its sent out.
As part of the protocol, the data cannot be discarded until there is a delivery confirmation or the FIFO is full. The system must use the standard GSM status messaging to see if the SMS was deliverd.
There also needs to be a LCD to display these channels locally at the system. I also think that a few push buttons will be needed to set (initialize) the time during system setup along with a reset/wake of some kind to power up the LCD. LCD if not used needs to go into a power down state.
The voltage and currents that I need to measure are of high magnitude. So stepping down the voltage, followed by buffering will be important. For current, a hall effect sensor would be great. Sense resistors are very lossy.
I have a PIC in mind, but we can certainly discuss it.
The complete system will have to be powered off a 48V DC. So a 5V LDO or a switching regulator will be required. LDOs may be too lossy for this, but again, we can discuss this.
As a deliverable I am looking for two/three fully working prototype in addition to the schematic files, layout, and C code for the PIC, along with some test data to prove the working.I am not perticular for any tools used in the development.
Thanks
