Archiving photographic work: negatives, CDs, digital files

Hi there, I'm a freelance music and travel photographer. I have many photographs in all formats from the past few years; various negatives, some scans of negatives, CDs, digital files, contact sheets...etc I need to archive and have all photographs filed somehow. In one place. So taking all my various files and saving them to one central system which is easy to use, refer to, and cross reference from. The photographs I have scans from neg for - some of them are low res. I'd like all high-res scanned. The ultimate idea is that I can quickly refer to, and gather high res images of any artist i've photographed, at any time. The archiving system also needs to be easy to use so that I can keep it updated, too. The person who does this will ideally have great attention to detail, and be careful and considerate when handling delicate materials like negatives etc. Thanks, any more info needed just let me know.
