PHP SEO Tools

Below is a list of 15 seperate SEO-based tools which I would like to have built. These tools should be made with a basic CSS design which is templated, just like the tools already at [login to view URL] All tools must have a CAPTCHA image, must NOT use register_globals, and must be PHP5 compatible. Cloaking Checker ([login to view URL]) -Enter a URL and compare how search engine sees it as opposed to a real web browser. Google Datacenter Search ([login to view URL]) -Search keywords/phrases through different Google datacenters. Keyword Suggestion ([login to view URL]) -Find related keywords matching your search (preferably by grabbing the results from a page from Google with 100 results on it, then analyzing the keywords and displaying the top 10, since the Overture tool is no longer around and Wordtracker doesn't allow cURL from their results pages) URL Redirect Checker ([login to view URL]) -Checks whether redirect is followable by a search engine or not Domain Availability ([login to view URL]) -Checks for available domain names (at least com, net, biz, us, org, info, mobi, ca, in, cn, [login to view URL], jp, [login to view URL]) Link Price Calculator ([login to view URL]) -Estimate how much to pay for a link (use your own algorithm, including PageRank, Alexa rank, Alexa visitors per month, backlinks from Google, backlinks from Yahoo!, backlinks from Bing, and indexed page report) Reverse IP Lookup ([login to view URL]) -Searches for all other domains hosted on a given IP address/domain name (using Bing's “ip:” function) .htaccess URL Rewrite ([login to view URL]) -Convert your dynamic URL into a short friendly link. Google AdSense Calculator ([login to view URL]) -Quickly calculate your AdSense earnings based on page impressions, average CTR, and average PPC Social Bookmark Checker ([login to view URL]) -Checks the top 10 (minimum) social bookmarking sites for links to your site and provides a report with total number of links per site. Domain Age Checker ([login to view URL]) -Displays the age of your site according to various archive sites. Domain Typo Generator ([login to view URL]) -Displays all possible human typos for a domain name (all keys around each character should be possibilities and should be listed in a text box for easy copying out). WYSIWYG Editor -Visual code editor, color codes HTML and PHP code, allows you to edit the page visually or as code. W3C Validator -Scrapes validation information from [login to view URL] Article Rewriter -Rewrites an article with HTML replacements for certain characters randomly to pass copyscape. (rewrites with the HTML hex code for certain characters so users see the site the same, but copyscape would not pick it up) All of the above tools that have websites in parenthesis should be *clones* of the pre-existing tools on those sites. The last three tools are NEW tools that are not available anywhere else, so you can ask me as many questions as you need to about them to understand what they do. All of the tools must work before payment is completed - and if I think that an outstanding job has been done, I reserve the right to pay more than originally agreed upon. All of the tools need to be automatic and must not put too high of a load on the server. Please do NOT use AJAX or databases - all data should be dynamically pulled. Full instructions must be provided for installation (or an installation script for permissions settings should be included) - preferably, the scripts will not require installation, just uploading. Please contact me with any questions - I am looking to have these done within a week or two. I expect progress updates at least once a day, preferably every time a script is finished. Once these tools are completed and I have sent payment, full rights to the scripts will be mine, and you will not be able to use/distribute the code. Feel free to use pre-made classes, but if you do, be sure that they can be sold freely. Thanks for looking!
