Escrow! Need a script that will create unique content for me

hey, I need a software that will do the following. 1. I'll be able to paste an article into a box. 2. When I run the script, it should fetch synonyms for all of the words in the article and automaticaly put them into the article in a spinnable syntax --- {synonym1|synonym2|synonym3|etc} 3. Each time I run the script at this point, I want it to create an article by randomly selecting one of the synonyms for each option. 4. I need to be able to shorten the article to increase uniqueness of the article. 5. I need to be able to tell how unique the created article is compared to the original article. 6. I need to be able to insert keywords into each article (with the ability to set keyword density to whatever I want) 7. I also need to be able to fetch articles from [login to view URL], [login to view URL], [login to view URL], [login to view URL] It's very important for me that each article the software creates is at least 70% unique from the original and that each created article makes sense. I want each article to be good to read and perfectly comprehensible. The Budget for this is $150.
