Visa run from HCMC

Does anyone know what companies do a border run to get a visa? How long does it take and how much?

I had a c-2, renewed once and now they say I have to leave to get another.

Everyone I know does it on there own (as I did prior to TRC). Get the bus to Phnom Penh, apply for your visa there (6moths easily available and 12 month on occasion).
Good way to relax for a couple of days and easy to do.

If you look around this site it has may ways of renewing your visa and not leaving the couny.  The big tip is find a good travel agent they can do all this for you at a cost of between $50 to $150.
