Custom Wordpress Plugin

I am looking to build a Wordpress plugin that will let users create some sort of a content slideshow. One idea I have is to make use of the <!--more-> 'Read More' tag that is provided by Wordpress. So, if the blogger has to create a slideshow of 10 pages, then will post all of that content in the same post and will separate the 10 pages of content with the <!--more-> tag. This should provide a 'Next', 'prev' button, and the url for each of these 'slides' should be appropriately suffixed with a #parameter. That is, if my article url is [login to view URL], then slide 1 (i.e. the content after the first 'Read more' tag) should be [login to view URL], slide 2 (content between the second and third 'Read more' tag) should be [login to view URL],etc. I am planning to pursue the project only if it works out cheap. So, please bid appropriately.
