Many designers have added code on my pages. I need it cleaned up. Pages are all functional - they just need to be search engine friendly. Adding keywords and tags etc. Need top 10 ranking on Search Engines for 30+ different keywords... (Budget: $100-$150 USD, Jobs: HTML, Internet Marketing, Link Building, SEO, Website Design)
