BTW, and you should know this: as a VIDEOGRAPHER, you don't "film" anything.
Usually I am one of the nice guys here, but in this case, my opinion is much like ittigger's. Seems like DJing will be a dalliance for you. If the water turns out to be too cold or the pond is too crowded, you will step right back out. And from the very little info you have provided, you can't expect much solid help to come back to you. At the absolute minimum, you need to know the minimum and the maximum you want to spend on starting your "business". Obviously you haven't even started a business plan, yet, or you would at the very least, know that much.
I said $4000... well that is what I think is enough to buy basic quality gear for events up to about 200 people. I'm not including cables, mics, music, BACKUP gear, and computers...... as you will likely want a backup computer unless you have some other backup plan.
Do your due diligence, create at least a bare minimum business plan, and then ask yourself if you really want to DJ.....
I understand that I don't actually use film, however that is still a term that gets used.
Also, I know I need a business plan. That's why I'm on here asking these types of questions, to find out what all I need to get. Keep in mind too that my original question here was about suggestions for amps. I appreciate the input overall, however it seems like this is staring to stray wayyyyy off course.
