I don't know where you are, but in the UK $30 (so £19) or roughly £160 a day is a very low rate. I would say that, depending on the location, the normal rates are from three to ten times this figure (depending on area of expertise).

[Edit - any time I see "daily rate" I think of contracting - £160 a working day as a salaried employee is probably on the low side, but nothing exceptional].
