Where to go in BKK for assistance in filling out Thai paperwork?

Hi all. I have Thai Social security paperwork to fill out, as well as being in need of a rough translation of the notification paperwork that goes with the forms.

Are there shops in BKK that will handle that kind of work (i.e. fill the forms with me right there and then)? I'd obviously need someone who has decent English skills, although only oral translation is needed. I have several forms and I guess it could easily take one hour or more.

I thought of these little lawyer shops I see around town; they obviously cater to farangs, but I suppose that it could be pricey.

Thai people I know or work with are not an option, or only last-ditch.

Thanks in advance for practical info,

NW
