Has anyone UK based used an agency who can handle the entire application process for returning to Thailand?  I'm in Scotland right now,  but will want to return to Thailand next month.  I have so much to deal with here,  I'd really like to just hand-off the entire process to someone who has experience can take handle the whole thing step by step.

 

If anyone knows, or has used such a service, I'd very much appreciate the details, and about how much money I'd have to throw at this to make it all someone else's problem.

You'd have to provide them with all the information required so just as easy to provide it to the Embassy direct and cut out the middleman.  It's currently only a short list of documents followed up with a hotel and airline booking.
