What are the details and requirements for the Non-Immigrant Visa category B-A (Business Approved Visa) in Thailand?

Non-Immigrant Visa category “B-A” (Business Approved Visa)

Question 1:People with this category of visa can stay in Thailand for one year and it can be renewed after one year period. This visa can be applied if a person wants to work for a company or organization. This request is sent to the immigration office and is only granted on their approval...This correct ?

Question 2 - If you are exporting from Thailand. Would the company with whom you dealing, count as a/an company/organization/employer?

Question 3 - The funds required to be shown as per [members only] would that be a monthly income? And must it be paid by the "employer" themselves.

PS Sorry for the lengthy post. Tried to fish for some information before rambling on asking aimless questions.
