Website Submission SaaS

I am looking for a developer to finish a web-based SaaS application that would automatically submit links, articles, videos, website URLs, and ping website to top relative directories. Most backend is already completed: <[login to view URL]> admin 6464240199 Now I need these 6 areas do automatic submissions for members (I provide the list of specific websites to submit to): 1. Article submissions to 40-50 article directories 2. Video submissions to 40-50 video sites 3. Press release submissions to 25 press release sites 4. Podcast submissions to 40-50 directories 5. Submit URLs to top 400-500 directories (Example service <[login to view URL]>) 6. Ping social bookmarking websites (example: [[login to view URL]][1]) It maybe enough to install a couple of scripts to make everything automatic: <[login to view URL]> can be used for pinging. <[login to view URL]> can be used to submit websites to directories, article directories, and social bookmarking sites. Another script can be used for video & podcast submissions - but I am open to your alternatives. You can view our competitor here: <[login to view URL]> The budget is $250 dollars. You MUST have experience with developing web-based service programs. Thank you.
