Thanks all for the reply.

Actually, the 504 course will be run by: Ed Skoudis, and the course 560 by someone else and I am planning to go for SANS in Singapor , I am thinking to take the basic with Ed in 504 and I can continue self study and practice, and since he is the author of 560, defiantly I will get benefit and he will guide me to the right direction. The 560 course will be in London by some one else (that’s why I do not want to take it). Any way my concerns is if I take the 504 course with Ed, can I start doing pen-test for network or I need to attend 560???

Also can you help me in the following?
1. What is the best list of books to start and become expert in pen testing?
2. Any video or other resources  I need?
3. What is the offsec course.

Thanks again for your support and guide.

Thanks for the reply and sorry for posting the subject twice.

my experience in security is manly with network security, i have lots of certification in this side (CCIE Security, Juniper Specialist, and others) you can say in the security as a (firewall, IPS, VPN, ..etc) i am expert in most of the top vendor.
Also i am expert in information security (I am CISSP, and CISM certified) and I am specialized in ISO 27001.
The week point I have is I do not have any experience in programming  .
Related to OS I have little knowledge
I am working as security consultant and would like to enhance my knowledge and be Penetration tester. For the pen testing I know the basic theory part but no hands on experience at all 
My plan is to be a network pen testing then focus on application and DB pen testing. I start reading the bible in network security for Eric Col. And planning to go for SANS training  after 2 months.
Now to achieve my aims to be expert in Pen testing. I need your support and guide of what to do and which training to take (SANS 504, 560)
BTW, my company depends on me to add this service to our customer. So please I do not want to let them down.
