actually, as you are in the non-paid section, you may not have a right solution for this, because there is already 2 paid solutions that offer commercial-like Ticket engines for vB... i suppose you do not want to pay for them, reason why you ask for a free one, but i would say as all the others, that paying for something that will bring you profit is just a balance of things. the guys work a lot to offer you full products for your needs, and from what i know, they work well on support too..
