Tips please Amazon & Aliexpress Affiliate sites

I have recently purchased the Aliexpress Plugin & Prosociate the amazon plugin for Wordpress. I have also already purchased 20 Niche related domains.
What i am wanting to do is create one affiliate website per day everyday until i build at least 100 sites.
My idea is that is that i will build each site with either aliexpress plugin or prosociate plugin.
I will setup a facebook fan page for each website. i will rapid index each site, i will also submit my site to search engines.
I am currently looking for a good plugin to automatically post to facebook, twitter, etc.. any suggestions would be great.
I would like to outsource most of my seo to get my pages ranked to make this whole process go much quicker.
The idea is that i want to set up each affiliate site to run on autopilot and need very little maintenance since i will have so many of them, i dont see this being a problem with wordpress and having these plugins
So pretty much i am just looking for any suggestions on how much money i should put into each site's Seo or anything that might help each of my sites be more profitable.

Thank you in advance for any help

Micro Sites Empire Building Need $$$$ Bucks. If I suggest I would Build 5 Big Authority Websites Instead of 100. Still for 100 Sites you need at least 5000 USD.

It depends on a tons of things. First of all, you re gonna design the website by yourself or not? If so, you can start with on site SEO free of cost! Then you can try off site SEO, that depends on what you are exactly looking for! Backlinks, Do follow, press release ... a lot of things like that. So the price is not predictable unless you know what!
