Welcome to Webmasterworld!
There's lots of online ressources for fonts, but probably you might want to check Linotype, since they are the font company out there.
There's nothing for free though, but you should be able to licencse single fonts for acceptable amounts of money. If you need a CD, try considerung buying a "Font Collection" CD since this is more value for money.
Considering value: the fonts and CD's they deliver are VERY professional! Even with extreme scaling the fonts have no ugly edges or spikes or flat curves as you might encounter with cheaper or free fonts. Also you always get the font both in Truetype and Type1 format.
Be careful however on the licencse agreement: the cheapest offers only include licencses for your personal use (where personal means that you CAN - of course - create commercial products, but that YOU are the ONLY person allowed to WORK with the font).
Keep in mind that a font - as simple as it may look - is a highly artistic piece of work. It's creation is extremely time consuming - usually a font artist spends a year or more working on ONE single font!
