copy website from one domain to another, both with Plesk, and some light editing

I need to copy the contents of my site [login to view URL] to [login to view URL], and very slightly modify it as described below: 1) remove the PSC logo and replace it with the logo in the attached file 2) alter the colours so that everything in green is the same light blue as the logo 3) alter the tsxt slightly (text files will be supplied) 4) make sure all the links still work, and link to umbrellaservices not psccs. this includes email links sending to the same name, but @[login to view URL] [login to view URL] is hosted by 34sp and uses plesk 7.5, [login to view URL] uses plesk 8.3 also if you could let me know how easy it would be for me to edit text in the web pages in the future. This should be a pretty simple job, I just don't have the skills to do it myself
