I believe u not suit the job yet.
1. You dunno how to quote prices means u dunno where u standing n ability of ur self too.

2. You aint businessman yet,

3. You cant simply calculate the cost base on ur personal salary,  cause u dealing with human, flexi, complication n bla bla

Just work out with pr or start low to earn business with out burden .
For example a local bangla can quote me rm 10k for simple cms (web), local student quote me rm 5k but i outsource to usual software house for rm 800.
Is not their ability, is the job n skill,  bangla think malaysia is rich n can chop . . . .
Student think other can charge 10k why not they charge 5k but they lag of the ability n responsible to complete it. They told me each day they delay, they fine them self rm 50 (0.1%),  is the best from them but standng on client site will said this is bs . . . .
