That's easily done if you either have the old official links to the isos or the iso's name. I can only serve with a few:
Microsoft Office 2003 Standard: OfficeStd.exe <<< no iso, but installer
Microsoft Office 2003 Professional: en_office_2003_pro.iso (not original MS-link)
You can download the Service Pack 3 update for the standard version of Office 2003 directly from Microsoft: https://www.microsoft.com/en-en/download/details.aspx?id=8
or use this MS direct link that I merely post here for posterity.
Iso-names of other MS Office versions you can google for:
en_office_xp_pro.iso (includes Frontpage)
