I am looking to get a basic rundown on the time and cost that would be required to develop a WP plugin. This plugin would do two things-

a) Build sales landing pages

b) Split test pages with analytics

The sales pages would fall under 2 categories

a) Jumbo images with info box in middle with a sales message as well as opt-in area containing inputs for name as well as email and a call to action button.

b) A page for a headline as well as under headline a video area and the same opt-in content area for inputs as well as call to action button.

Lastly I would like to be capable to split test pages to be able to see which pages are converting better along with some metrics that will permit the user to see what type of traffic they have has to each page.

Desired Skills are MySQL Administration, HTML and PHP
