PageRank calculator and URLs/link graph visualisation in PHP and Javascript

I'm looking for a good dev that knows his stuff is able to provide insight on tech choices and doability of projects/specifications. Looking for an english or french speaker (doesnt have to be fluent but communication must be possible) and ideally someone that is willing to work with other related projects in the future. Also, must be available to work per hour (at a fixed rate) to fix/upgrade stuff or implement new specs. _____ I need someone to make me a web tool that visualizes a link's architecture from a database containing URLs and links (source / target). Also, the tool should be able to calculate the PageRank of all the pages from the list of URLs and links. _____ Some details : - The visualisation graph should have clickable nodes that open a pop-up to display information about the page that was clicked. - The visualisation graph should have different modes : ----> Show all links ----> Show only first link found in the db ----> Visualize website according to directory structure ([login to view URL]) - When a node is hovered or selected, all links (incoming outgoing) should be displayed if the visualisation mode is not currently set to "show all links" - Nodes (pages) should have a different size according to their PageRank These are just a few details, full specifications and details will be provided.
