Hello.. I understand that you have a website and you want to convert it to wordpress. Your are right that it will be a simple process, as you dont want to change the design and contents. However, since it will be done with wordpress, you will be able to manage the stuff now.
It will be intersting to review your current website, so if you can share the link, we can review it.
I have created and customized wordpress themes and plugins in the past. It appears to be an interesting job to me. Looking forward to discuss and work on this.
Tx
