While we are there to help, we are all volunteers here. So asking for complete video’s and PDFs to solve a user-specific problem is not the friendly thing to do.
If you don’t know what you are doing, but yet go out to buy (in this case) gear we would not have recommended to you, it’s a bit odd to come running here after the fact when things are not working.
There are many articles on these forums and over at the main blog about things like hooking up speakers, setting correct line levels to avoid blowing things up and best practices for picking gear. I would suggest you use the search function and start reading up.
If you end up having more specific questions on parts of your setup, we will gladly help you.
P.S. I would think there are more “certain” careers to start to generate income than DJ-ing. Just my three cents.
