Need to do my first ever border-run at the end of the month.

Because of my location (Kanchanaburi) being about as far from a suitable border as can be, am considering using an agent, instead of undertaking the trip myself. If that's possible.

Do agents perform that for people?

If so, what's the likely cost and procedure?

How do I find a trustworthy agent?

Anything else I should be aware of?

Experienced help and advice would be greatly appreciated.

Thanks in advance.
