I have done some research into your question, and I have come up with
many different options.
Firstly, there are the "Firewall Appliance" options. These are
plug-and-play boxes you simply put between your network and the
Internet, and are normally configurable through a simple web-based
interface. I have worked with SonicWall products before, and their
SonicWALL PRO 100 product seems to fit your needs well.
It offers the whole range of standard firewall features, including
those you mention in your question. It optionally offers services such
as anti-virus protection and web content filtering for your employees.
This is my strongest recommendation. There isn't much a small business
could need that this firewall appliance couldn't offer.
More information on the SonicWALL PRO 100 can be found here:
http://www.sonicwall.com/products/PRO_100/index.html
It can purchased for $1,389.00 at firewalls.com at this address:

Roughly on par with SonicWALL's PRO 100 product is WatchGuard's
FireBox 700. It has almost as many features as the SonicWALL option,
but is a bit more expensive, at $2,000. While it really has no merits
over SonicWall's product, here is a link to its product page:

And, in case you wanted to buy it, CDW offers it here:

Another popular option is to take an off-the-shelf PC and use Linux to
turn it into a "home-made" firewall. While this doesn't have the
plug-and-go simplicity of the firewall appliance solutions, it has the
advantage of low cost and high potential for customization... and also
the potential to be made completely useless by a simple mistake.
The exact procedure for creating a Linux firewall varies according to
your exact needs and whim, but these websites should contain enough
information to get you started:

http://www.grennan.com/Firewall-HOWTO.html
http://www.linuxworld.com/site-stories/2001/0920.ipchains.html
My personal recommendation would be the SonicWall product. I have seen
them in action, and worked with them personally. They are very slick,
very powerful, very easy to manage, and quite a bargain.
If you have any further questions, be sure to drop a request for
clarification, I would be glad to help out more within the scope of
your original question.
