We from ispconfig.org offer the remote ISPConfig installation service for 79 EUR. You find our contact details here: http://www.ispconfig.org/imprint.htm
You have to make sure that your vps runs a empty basic install of a linux distribution that is supported by ispconfig 3 and it must have enough ram to run such a setup. I recommend to have at least 500 MB and that you use debian linux. If you had tried to install ispconfig yourself ain the vps already or you had a different controlpanel installed before, you should ask your provider to reset the complete vm image.
