I actually enquired about this with an agent for applying in Vientiane. The issue back then was, while I had the money, at the time, the funds hadn't been sitting in my account for the required 3 months that Vientiane demands (which i find ridiculous). The agent wanted 27K, which is relatively cheap compared to what they're charging now.
I then considered that given no other consulates are requiring the funds to be there for 3 months and I meet all the requirements anyway, why would I waste my money on paying an agent when I can do it myself?
I'd rather spend that amount on a business class ticket to Taipei, or a business class ticket to Saigon with change leftover and get it done in one of those places.
