Basic PSD to PHP\CSS - Small Block

I'm regularly changing my website design, block by block (small parts, usually its not even a 5th of a page and doesn't require complex slicing like header\footer areas). I'm looking for somebody quick (with high availability) that can convert the PSDs to PHP\CSS codes when I need it. Please quote me per 1 simple job, and please offer your service only if you're available for daily\weekly jobs. Thanks.
