Add links to wordpress-template

We have a wordpress website with estore plugin. Now we only have a store frontpage showing a list of products of just 1 type. We want to change this and add links on the frontpage to show products based on tags, category and type. If you're familiar with php this should be an easy job taking max a couple of hours for a good programmer. If we are satisfied with the job we have some bigger projects in the future.
