Wordpress Mod - Infinite Scroll Mod Installation

Hello, I have a website with many many blog posts and have been to other blogs and have seen the use of INFINITE SCROLL used with great success. I tried to install it on my blog but there seems to be an issue with the template/style I'm using and the implementation of the Infinite Scroll mod. Specifically, I need the infinite scroll to work when a visitor browses to the [login to view URL] where all blog posts are listed, when they scroll down to the last post allowed on the page (i.e. 10 per page), the next 10 are loaded automatically with Ajax or whatever the Infinite Scroll script uses. I consider this a VERY simple project and would like to hire someone that has implemented this before by making alterations to the hack/mod that fit in with the CSS attributes of custom themes. That's the problem I'm facing, infinite scroll not working because of this custom theme I am using so, whoever can do this for the right price, the gig is yours.
