Design a logo for my business

I need a logo designing for my little business - it needs to be square, as it will be my facebook image as well, and it will also be my avatar for various social media sites. I would ideally like a square one and then a longer rectangular one for compliments slips and for stationery. I'd like to see some examples of your work before I take on someone to do the work for me. I like things that are clean and modern in look, as well as simple and easy to identify. My website colours are black and orange with white, so those three colours will be the ones I want in the image. My business is English tuition and my company name is Emma Lee Tuition.

I will eventually be upgrading my website (I'm a startup, so things get upgraded when I have the budget!) and facebook header etc over time, so there will be follow-up work if you want it.
