Avg Bid (USD)
Project Budget (USD)

Project Description:
This is a small job for someone who knows how to replace an existing web site with a new one, and not lose the Google ranking or incoming links. Two people who know how this is done have sent me the code (both different!) and directions, but .htaccess file and other stuff is foreign to me. I'm not going to risk blowing it. If you can help with this, great. If you can show me how to do it, better, but only if it's hard to screw up. The new site - maybe 20 pages - is nearing completion and completely replaces the old (smaller.) No old pages will remain in the new site. I thought this was HTML, but I don't see that in the job list. XHTML?

Skills required:
Anything Goes, HTML, XML
