Hi there!
I am not a professional designer though I have passion for creating logos and some sense of balance and colour:) So, I've made my mind to try to do something about your task and here come the results. Hope, they can be of any use!

As for the colours: it's possible to change them (I've chosen such as the background is white, but when (and if) you publish one of them on your website, you'll get a draft with a transparent background and so the colours will become lighter or darker dependent on your preferences).
