Hi hwzone,
I have very good experience of working with dsPIC & PIC micro-controllers, for applications ranging from Power system to interface and multi-point communication systems. Recently i did boot loader for dsPIC33 & in past i have worked on boot loaders for PIC18 as well as PIC16. I can do it for you in the way you want it for your PIC18F14Kxx.
I look forward to hear from you soon.
Thanks & Regrds,
Tushar
