I have a .PSD template of a site, I want to turn it into a nice WordPress theme, and used for my own personal use. It doesn't have a lot of fucntion like the normal wordpress themes do, but on the other hand it has a few functions which are a 'bit odd'. In any case, if I hire a designer. Can I tell him, "Do the site. Upload it on your own server to see if it'll work. If it does work, I'll send you $250, you send me the site, then I send you the other $250" ?
