Just an update: I found I can mail film to BKK and get pro processing and printing by mail (IQLab). Prints up to 20x30" can be mailed, so the plan has become much more simple. To save money, I'll just get the processing done, then scan film at home, print proofs and up to A4 at home, and transfer any files to be pro-printed electronically to BKK. Incidentally, I found the cheapest place on Ebay to buy Fuji (and other) film in most popular sizes to be located in BKK! He'll give a further 30% (approx.) discount for buying direct for Thai residents. Films Carnival! He offers prompt service and fresh film from what I've tried.
filmscarnival@gmail.com I apologize to anyone offended by such a shameless plug, but in this case I had just spent days going to cities within a 2 hour radius without finding a single source for film, so I figured someone else could be in a similar quandary.
