Multi-Domains - Can someone install it for me?

I've been struggling with this plugin and I think it'd just be easier for me to ask an expert to install it for me. I thought I did everything right but I'm not too sure since whenever I create a site, it has an Index page, like it's not connecting with my WordPress installation. I need someone to do it all for me (I can pay a little bit) or give me step-to-step instructions that are a little easier to understand. Thanks in advance.
