WEB Design, Script Installation - MUST KNOW DNN and Asp

I am moving my site from joomla to dnn dot net nuke. I have bought a script and need it modified, and new scripts installed and linked to the home page template. We are a small animal breeder so we do not have a lot of money. I am looking for a long time relationship not just one time. I need someone that can help me along the way and if this goes well I want to move some of my other sites also.

I bought three scripts and they were installed but I don't know wht happened to them when they installed the template.

I would also like to add some more scripts (purchased) to the site and I am always open to suggestions.

I know very little about this but I can add all the data once the scripts are installed.
