Building Tier 1 Links, do I need private proxies?

Hey guys, I spent a few weeks with a friend building a website. The website is run on WP and we are monetizing it with CPA and we will be building an email list. It is an authority site. It is currently hosted on a shared hosting plan on Hostgator (we're pretty broke). Anyways, it's my friends job to build the website and use bought tools with our money for T2 + T3. My job is Tier 1. Also, we are doing this as white-hatty as possible, since that seems like the safest way to go for us noobs.

Anyways, I recalled from somewhere that it is necessary to have private proxies when linking to your money site with Tier 1 sites. I still haven't found a clear answer and just want to confirm my conclusions on this topic. Would I need 1 private proxy per link?

So for example: if I had 5 web 2.0 sites, 5 social bookmarks, and 5 article submissions; would I need a total of 15 proxies?

Sorry if this question has been answered or is extremely nooby.

No proxies needed

if you build low numbers like your example you can do fine without proxies. If you want to build more you will need some private proxies

Proxies are needed when you plan to create thousands of backlinks in a very short period of time. As you mentioned a very little amount of backlinks, then you don't need to use private proxies.
