car: 03 Honda Accord LX V6 Sedan, Automatic
goal: transmission swap to 5 speed manual

i have an idea of ppl that can swap trannys but the average cost ive seen from them for older cars was 1200-2000

question is, what cost would i be lookin at tryin to get a shop to swap the auto to a manual?
would 6 speed even be possible?
any specific damages i shoudl worry about besides "the car may never be the same again"?
would mechanics even be able to mess w/ an 03 accord, being new ?
