i agree with above, just spellcheck it mate. makes it easier to read.
Also, trying putting quotation marks around speech and making it easier to read, so we know when a person is talking, as it's quite tricky to read atm.
Try and get you're timing sorted as well, it seems to be jumpimg around a bit.
other than though, good story. good idea as well and if written well, could be one of the best stories on the site...
