Local Business SEO with Local Place sub domains

Dear Warriors,

This is my First thread in Warrior Forum. I have an idea to target Local Business.
1. I currently own 150+ Local Place Domains. My definition for Local Place domain and subdomains :

If the name of a city is city1 : My Local place domain is incity1.com or incity1.net.
My Local place subdomain for hospitals and doctors will be hospitals.incity1.com and doctors.incity1.com .

2. Every Local placed subdomain will be a different website , It will be updated with relevant articles and Directory listings.

3. Every local placed domain(LPD) will be a top level website for all Local place subdomains (LPSD)

4. All LPD and LPSD will be SEO optimized with all white hat SEO techniques .

5. Every LPD and LPSD will have one or more SEO link wheels or Pyramids with micro web sites(Blogs and microblogs).

6. All micro websites will have a Fullmonty run with senuke every month.

7. Once my LPD and LPSDs have landed in first page in SERP I will start monetizing them. But I will wait at least 6 months to do so.

I already own the domains I need and SENUKE permanent license with me.
I have my own network of own proxy servers, 3 windows servers in three differnt locations with my own senukex license.
I have six employees to work for me , already recruited by me.

Wordpress will be my CMS

Please let me know your thoughts on this Idea. Am I doing anything wrong ? your ideas and suggestions will be appreciated .
