As was stated earlier, a conservator is going to be an expensive proposition. Since most of what you list is paper related, the suggestion of scanning, or taking photographs, is a good one. I've done this in the archives that I have worked in over the past twenty years. There are other companies such as University Archives, Brodart and Hollinger Metal that you can purchase archival folders, sleeves and envelopes from. Anything that you use needs to be acid free. I have used Itoya products for rehousing disbound scrapbooks. HobbyLobby sells these. Once I have rehoused the scrapbook, I use Hollinger boxes to store the scrapbook in.
You can also relax rolled photographs yourself. Follow this link for a good explanation of the process.
