Copy Wordpress Site to another domain

I need to copy an adult wordpress site to another domain. So the new domain should not to have anything to do with the old site and run all the plugins by himself. I need all the pages , all pictures, all functionality of old site to be on the new one and to work 100%. The orginal wordpress site ([login to view URL]) need to remain the same and untouched. The new one ([login to view URL]) need to have all [login to view URL] pages, categories, functionality etc. , but all that to be on his own database. It's not a big job , so i cannot pay more then 30$.
