PHP or Ajax contact form - Reposted

Hello, I need a small, contact form that looks good but is simple. What will you charge me for this? It must only have Name, Email, Message in the fields. See attached pictures. Additionally it must float on top of the website by default, with a arrow button that can be clicked to hide the contact form. Once a visitor landed on the website the contact form must be visible by default. Also, when changing to a different page, the contact form must be visible by default, even if the user did hide it on the previous page. Once a user completes the contact form & clicks Submit, it must redirect them to a Thank you page. I must be able to create a Thank you page for each individual page on my website and let the contact form for each page take a visitor to that specific page's unique Thank you page. You only create 1 contact form, I will implement it on the website myself for each individual page. Once the contact form is hidden, the Contact button will be flashing to attract the visitor's attention.
