MicroSD card system for PIC24f

You are bidding on a rolling file system for writing sensor data in CSV. to a Micro SD card. The processor is a pic24fj256gb106. The data is two consecutive 16 bit numbers and a time stamp. The data is recorded to a log file on the SD card then at a specified time intervals down loaded via modem, then the log file is archived on the sd card using a rolling file system. You must be familiar with Microchips Micro SD card file system via SPI. The project currently runs on MPLAB using X18 compiler. This device is currently running and mounted on a server withMPLAB and PICKIT3 for remote assess. This is a straight forward job for the right person. This device will require ongoing development work at a later date. Only responses with the phrase " lifetime opportunity company" will be considered. Thank you for your time. Regards
