Is all of that web traffic that should be proxied by Squid, or is
there other traffic as well that won't involve Squid?
What is the expected bandwidth that will be proxied by Squid?

3 years of 20 Mbps is not realistic on any budget.
20 Mbps is roughtly 2MByte/second. Assuming you have a bursty usage
making the link ca 33% used on average over the day this is ca 56GB
per day. Counting low with only 40 weeks of activity per year, 5 days
per week this is 11 TB of content per year..
Assuming 30% of the content is cacheable and stays in the cache it
still is 3.6TByte per year..
Note: Most people find that the increase in hit ratio diminishes after
about 1 week worth of cache..
