A word of warning (sorry to be discouraging)...
Be prepared to have income imputed to you. My hubby lost his job, was unable to obtain a salaried position, so he obtained one of the many commission-only positions which were offered to him, hoping it would work out. (After all, he has child support to pay, not to mention all other expenses!) Well, regardless of the many documents presented to the court demonstrating how much he had actually made in commissions, what his expenses are, etc. the judge decided to impute income to him at over $10,000/annum more than what he is actually making currently, because she felt that he should be able to obtain such a higher paying job given his education/licenses. The print outs showing the dozens of daily applications for various positions, letters from institutions saying "sorry, but we put the search for a candidate for this position on hold" meant nothing to her. It's as if the entire state of today's economy was irrelevant. And there was very little we could do about changing her mind on the subject. We now have to wait another 3 months until our next court hearing with regards to this issue, and in the meantime find ways to pay an amount in child support much higher than we can afford.
