Your fat bank balance won't help or break you, if u have 1k or 100k usd the odds of getting denied is exactly the same. They only care about how long u have been in Thailand, the 3 *proof of* (especially 1k bank balance of at least 1 month old), and to a certain extend visa run in a row in PP (3 usually the magic number).
You will lose nothing by trying, ask agent that u will pay him when he succeed, I told him I will throw extra $10 after if he succeed, still got denied and he was a reputable agent riverside.
