Why on earth would you need someone to renew your Thai driving licence? It's an easy and straightforward process that you can do yourself at the land transport office, also for far less than 1500 Baht.
I bet they mean an account statement covering one year by that. At least that is what is asked here in Chiang Mai for the last years. They want to see if you kept minimum account balance.
