Mainly for the search engine traffic benefits I am probably going to start a link list!

Any advice that some of you link list site owners could give me would be greatly appreciated !
I will only be designing and overseeing the site, and will let one of my employees run the actual day to day stuff. My questions :
1. I am not looking to run a small link list, and have already put aside $5k for scripts and traffic if necessary. Is that a realistic investment? While I doubt I would have another Link-o-rama or Jaysxxxlinks ... I am not aiming low.
2. Is it worth buying cpc traffic to get the LL started? Is it worth buying traffic at all ?!
3. How do I get freesite submits. Should I try to get my LL listed on resource boards and other's submit pages?
4. How do other Link lists trade? Do they base their trades on the number of sites you have listed, the traffic you have, your google PR ?
5. Considering that I already profit around 20k a month, and will have one of my employees handle the reviewing etc, is it a realistic venture for me to take on? Is the link list market hard to break into and hard for new LL's to get into? While I am not looking for success in 1 month, I would probably think twice if it would take 2 years to see any worthwhile returns.
Really appreciate any advice you guys could throw my way !
cheers !
