Autoblog + longtail pro keyword analyse + search replace NO WP BUT CUSTOM

Background information: I have created the HTML already. I need now a developer to create the PHP to setup an autoblogger script. This script should have some requirements: 1. Users can add keywords. Based on these keywords blogs are automatically search by search engines and added to the database. 2. Feed urls can be added (with or without keywords) and blogs are created based on the url or keywords. 3. Blogs should be completely created. Not a small part (for example from a rss feed) should be used but the whole article. 4. Images (if available in blogs) should be stored on my own hosting. If no images are available the script must add default images based on the most relevant tags from the internet. EXTRA REQUIREMENTS: * For all blogs an analyse script should check the most popular keywords and add 5 of them to the tags part in the db. * Images from feeds should be automatically saved in the users image folder. Folder name should be called Autoblog * An extra page must be created where site owners can analyse long tail keywords like: [login to view URL] Based on the entered keywords the page should give users suggestions about the best keywords to use, is the competition high/medium/low, distance, save keywords to favourits (also the best suggestions in groups) simular to: [login to view URL] * If a blog with feed is generated a default thumbnail should be added. Based on the tags of the blog a related image must be searched from google(?) and added to the blog. SEARCH AND REPLACE * Search and replace: a special page must be created where users can add their words to search and replace. NOTE: MAX payment is given in the fixed price. I only do business with people with good reputation and this project must be finished in a few days.
