Wordpress Template Required

Need a fairly simple Wordpress template building. The design is 100% complete so no creative thinking required (although nay advice on extras for wordpress will be welcome), I can supply the design in .psd format or it can be taken straight from my site which is already coded in html & css (i.e a lot of the formatting and coding is already done) In essence, I just want to add a blog page onto my site and have it look the same. Wordpress is installed already.
