Create a website with CMS from PSD (PHP/MySQL)

Hi, I need a website with CMS (wordpress or joomla). The project has two parts: 1)PSD->HTML/CSS/Images 2)Programming CMS I can send you a similar website example in my messages. It's a "used cars for sale" website: It will have - Home page showing recent cars for sale - Inventory page: you can search for cars by keywords/brand/price/year/model/etc - It will have 3 or 4 forms and a contact page I will provide the PSD. The PSD is not done yet but I can show you a similar website. Please give me a rough estimation of the following: 1) How much and how long for the PSD->HTML/CSS/Images part 2) How much and how long for the programming part Thanks!
