How do I get free stuff?

I am a budding Digital DJ/KJ. I have recently moved to Ireland from the UK. (sorry !) I used to work for a company in the UK that supplied all the kit. I just turned up and used it. I have a very small collection of MP3s, (about 2000) and about 3000 Karaoke songs. I have some pro kit, and a laptop. I just need to get some things to be able to start making money. i am looking to get sponsorship, some kit on loan, or some freebies like promotional material, e.g, software, hardware, flight case, mics, headphones, lights, etc. Or just things like stickers, keyrings, free business cars, (yes I know you can get them on the net if you pay posatge, so that's not free is it?) or a trial gig where I can just plug my kit into an existing PA system, or amp and speakers. Please help!
