Hello,
Having looked at the brief project requirements, I think I can take this up. This is because I have got prior experience in handling Arduino boards with ATMega328 and I have also worked on a few 8, 16 and 32 bit micro-controllers. With respect to GPS and GPRS, I have handled them at my previous work to actually get the information from gps and send present location to a recipient through mobile data. To send SMS, i have handled GSM modem uding AT commands on a home automation project. Hopefully, with all these knowledge, I believe strongly I would be able to finish this job for you. For your reference you can look at my CV/ Resume
Thanks
