Here's an idea and maybe a good experiment that I've done on some tracks when I was on a budget , sub mix your trax into 3 groups Hi,mid and lows the send eack bus out into a three channel DJ mixer and work the crap out of it until you get the EQ and levels right as well you can always use old amps and home setreo eqs laying around for addition. I know a lot pros who use these techniques even to today. but when you can I recommend getting a comp and some other real gear

I know your on a budget and everyone has been there but "if there is a will there's way" :)
