can you attach something in hand drawing , of actually what you want to achieve. it will help me directly start on the project.

As the basic form you can choos a simple coat of arms form
like the examples here http://thumbs.dreamstime.com/z/vector-coats-arms-3494066.jpg

I would generally tend to a simpler form than to a more complicated but this is not a hard opinion
Regarding how the elements on the Shield should look like I don't hav a good Idea, so nothing i could draw here
