You don't need anyone to help you.
Each application is unique, there is no standard "format" or "template". The main requirement is having 500,000 Baht or equivalent in a personal bank account and possibly having to maintain that for up to 6 months at some embassies. Usually, except for Malaysia and Laos, it's enough just to have a closing balance of 500,000 Baht BUT make sure you have 6 months worth of statements.
The rest depends on what you do - easy to figure out what to supply, bank statements showing money being paid to you coming in, a portfolio of what you do, that sort of thing.
