stop being sorry. i was in the place you are in once and so was everyone else here. that's why you're here.
burning a chip is super easy. you buy a prom programmer on ebay or whatever they are cheap. you put the chip in it and read it modify the bin and then write it back. if you have enough computer skills to post on this forum you have enough computer skills to program a chip.
if you replace the chip with a larger one you have to 'offset' the program. this is also pretty easy.
