This project is pretty easy, but has couple interesting points.
50$ 3-4 days.
Code must be 100% w3 valid and CLEAN. Cross browser compatible. I do NOT need IE6. Just IE7+. However at least the design should have the same structure in ie6, not that top menu is at the bottom or something :))
Its business directory site, there will be companies listed. Only admin will be publishing posts (POST YOUR COMPANY button will simply lead to page where I will explain that companies need to email me their details and I will post them).
Categories in left sidebar + there should be filtering by cities (maybe just add simple drop down. Designer forgot to add it so its not in the psd).
Posts inner pages are simple - as you see in design just longer (with more details and info + some photos). 2 categories - regular and featured posts. Featured posts will be on top of all the rest posts. And featured will have more options - more fields for info such as "company website" and option to add photos.
Users should register on the site. I need them to register for 2 reasons - I want to send them emails using "email users" plugin + only registered users will be able to contact listed companies. Non registered users will see "login to contact this company" text. So I encourage people to register. I would prefer you to use some contact for plugin for users to contact companies..
For banners some simple banner management plugin is good. Sometimes I will add banners and sometimes adsense code using simple text widgets. (I think its natural that theme should be widget ready these days)
I think I cover all the points and nothing else needed
