ASP Website Server Move

I have a robust SQL Server data driven website written in asp and aspx that i need moved to a new windows server. the one we're on now has reached it's maximum upgrade and is running Windows 2003 and there's no way to increase the ram or to improve performance. we need someone to copy our site over to a new server, install what needs to be installed to make our automatic emails run, our videos convert and play, our pdfs and docs to watermark and overwrite, etc. we already have a new site in development, but until it is done, we still want to move this site to improve speed of searches and page responses.
