Bunch of people in the "Services & Recruitment - v2" forum likely willing to do this. Not real hard at all. You may have to pay someone $5 or so.
Thats not what the title says though. You said you want someone to help you install it for you. Anyways I've never installed multicraft but perpahs they have a wiki with useful installation information?
There are plenty of tutorials for this all over the internet. What do you need help with? Your post is very vague. You provide no information and no contact info. I'm sure many people could help you here right now, what is the problem?
