I want to distribute the internet to 150 PCs. Which software or hardware should I use as a best practice, which can give me the best output. I want to block some websites, whether I should use a hardware firewall, or I should opt for any proxy software.

you can block a website as follow
1. Load your Internet explorer
2. Click Tools
3. Click Internet Options
4. Click the Privacy tab
5. Under the Privacy window, Click Sites
6. Type in the site address that you want to Block and Click OK. Remember this technique only blocks on one site at a time. Parental control software will allow you to block multiple sites and categories.

I would prefer to have a hardware based solution, and that too not much costly. I have heard a lot about Watchguard and some other firewalls with UTM facility. Please suggest

I've had good results with IPrisms.  You can use them with or without domains, and are really granular with their rulesets.  They turned out to be much cheaper than the 8e6 models, especially if you work for a non-profit agency.

I doubt any of those solutions can avoid proxy sites.

One good strategy is to open only sites you need and block everything else.

You can never block all proxy sites, but most hardware web filters update frequently enough to get most of them.  There are a couple ways around that, but even whitelisting can be defeated pretty easily.
