Hi,
I have 1 year of exp in Liferay portal.
I have very well knowledge OOTB portlets in Liferay and
How to customize OOTB portlets using hook and ext.
You mentioned that you want customization on out of the box portlets like search, images, videos, surveys, Let me know your detailed requirement on this portlets.
And also you want your intranet site should work perfectly fine on IE7, That is also big task to run liferay on ie 7 without any look and feel issue. And surely I can handle this challenge in Ie 7 also .. :)
Thanks
Krish
