Just to clarify/summarize:
- web/db UNIX programmers: 1-2 days
- other UNIX programmers: 2-4 days, maybe a week
- web/db non-UNIX programmers: 1-4 weeks
- other non-UNIX programmers: 4-8 weeks
- all others: 2-12 months
Oh, I forgot to mention: anyone who could pick up enough *nix in a few weeks/months to install OpenACS still would not be qualified to administer a production-grade, publicly-accessible web/db box. A small intranet box, maybe, but not the real thing on the Internet.
You've probaly already thought about this, but it's worth mentioning in light of a recent thread about security and who is concievably qualified to administer public web servers.
