WordPress walks you step by step through set up if you read the instructions. If you can't do that then there are many tutorials on YouTube that you can watch and learn.

I would recommend reading some tutorials , watch couple of videos and do it yourself. It is quite simple once you have done it. First go to wordpress site, download latest wordpress and on that page you will find location of the wiki from wordpress to help you with installation (not all that great tutorial but still you can do it). Unzip and upload to your server in the root or the folder where you want it installed, assuming you have already pointed the nameservers . Create a mysql database and go to your domain in browser like http://www.mysite.com and it will point you from there, just write down the database details when you created a database(= server username+database name). hope this will get you started.
