Sign up process for DBS Woman’s World Card?

Hi, would like to ask those who applied for the DBS Woman’s world card on what’s the process like? I’m interested in combining this and DBS Altitude due to the pooling function of DBS points but I’m concerned about the income requirement of $80k. Saw many reviews which states that it should be no problem as long as one earns more that $30k pa but, what about if I’m self-employed? I have only been working for a little over a year but biz is slow and only recently able to earn $4k+/mth last 2 mths
