Nextgen gallery changes

I want to make some basic changes in the nextgen gallery plugin. Only a good PHP / Wordpress developer should apply. I am using the nextgen gallery plugin in my wordpress site to display images. However, the display is not upto my satisfaction. I want to make the following changes. 1) I want to repeat the Next and Back button which are at the bottom of the post to the Top of the post as well as to the side of the post. 2) Meta description which appears at the bottom of the post should be centralised. 3) I want to enable Ajax pagination at the bottom of the post. Which is not currently happening even though Nextgen does have coding for the same. Do not know which plugin is creating problem for the same. The link of sample page is [login to view URL] These modifications require basic knowledge of PHP or CSS. So awaiting your quotation for the same. Please note - There will be no milestone payment. There will be no payment release if all the three tasks above are not done. Kindly quote me for it. Regards Hitesh Bhasin
