Script to post/crawl/fill info on website

The problem: Example: I want to sell my old bike. There are many websites where I can post such an ad for free instead of going to ebay. The only trouble is that I would have to fill each website again and again if I want to sell this bike. The idea: I want an online interface (my homepage) were I can fill all info needed for those pre-determined websites and a script/engine will repost all info on those websites. The fields etc needed to be filled on those website to enable my bike to show up for sale are known to us (engine/script) so we only need to fill it on my homepage and no need of going to all those websites 1 by 1. Another thing is that we can schedule the script/engine to remove my ad(s) from those websites or repost it at a specific given time/day. Without such an engine/script I would have to refill the full ad manually each time I need it reposted (so it goes back to the top of the ads listing for better chances to be seen) Requirements: - Create this script/engine online + homepage that will collect data for it. - Create options like scheduler, deletion, reposting button etc - Job should be done in 6 days after it gets attributed to you. Procedure of bidding: I am a webmaster/designer myself and know exactly what I need and how it works. You will get my full (technical) assistance 24/7 on this as I always do with other providers. As it is obvious u may want to discuss the job first before making a final offer: 1- Bid first 30 dollars (not final bid) 2- Discuss issues with me thru p.m. as all agreements will be kept there. 3- Contact me and ask for an example of those websites so you know what type of script is needed and the job it will do while posting automatically. 4- Adjust your bid (higher) after all issues are discussed N.B.: To avoid automatic/bot bids I request u send me a pm stating exactly ‘Only_Serious_Bid’
