You know how to edit a template, at least you didn't say you didn't when I answered the question about the login drop down!
You're talking about making new layouts... Maybe it's best to start simple.
Initially it might be best to check the Resource Manager for something that matches your needs.
Then, if you're interested in learning you could start asking questions here like "how can I make this, look like this?".
Alternatively, if you have no interest in doing it yourself, someone might be able to make one for you. If you have a good idea of what you want. I can help with that if you're interested as can many others here if you have a budget.
Hope that helps
