In addition to the bitcoin wiki there's also plenty of ads on bitcointalk.org and #bitcoin-otc IRC I've negotiated for shell accounts, rack space, and even AWS instances.
Thanks to services like Bitpay most hosts accept Bitcoin now and if they don't email them with Bitpay's (or competitors) rate page showing no monthly fees, and next day bank deposit, and they'll go for it. What's to lose, Bitpay guarantees you will receive the price you ask for, provides an easy payment API, handles all the coins, and deposits it by end of day if you're US based.
What I don't get is why Gold/Silver websites haven't created a 24hr, live trading site using bitcoin for payment. Buy all the gold you want through Bitpay with insured and guaranteed payment, no need to phone agents to get a price quote. Maybe there is some kind of law regarding identity of payment or something I don't know about.
