Cost for a complete GSA SER setup… Please help

I had a guy to create GSA links for my sites. But he is not replying since a long period of time.
So I am planning to setup my own vps. Can you please suggest me the requirements for creating good quality, Tier 1, contextual links.

As per my research, I will need:
1) GSA SER software. [Mandatory]
2) A good VPS. [Mandatory]
3( Captcha. I understand that I will need atlease 2 captcha solving source. Is it mandatory to get GSA captcha breaker? xevil? 
4) Proxies [Mandatory]. But how many and what quality?
5) GSA lists and some service for web 2.0 addons.

I want this setup to be economical, but also I want to create the best quality links that GSA can create.

I would highly appreciate the comments from users who have real experience of using GSA SER.
