Design a Logo for an International Consulting Firm - Africa

Hey, I am looking for someone to create a logo for my international consulting firm that works in Africa. The company is called ikap Global LLC, and works to connect companies in Africa with other companies around the world. I am looking for a logo that promotes energy, innovation, networking and opportunity. The most important feature to me, however, is that it has a subtle touch of Africa. (I have included an example, in which Africa subtlety completes the outline of a lightbulb. I like the discreet nature of this example.) Whether that touch be including the outline of the continent or including colors, or a design that is "African" is up to you. You are the professional, and I trust you fully! Here are a couple of suggestions that I have had in mind, and the reasons for how they are applicable: 1) A bridge - Because we are the bridge between Africa and the rest of the world. 2) A lightbulb - Because we are bringing Africa into the light. (I have included an example of this one but please just use it as a template to get an idea. I want you to make some changes and improvements because I am not entirely satisfied with this suggestion. Thanks!) 3) Africa rising in front of a sun 4)A road/highway Once again, these are simply suggestions and how you choose to portray them is all the fun. I am looking for as many suggestions as possible (including different colors) so if you would, please send a couple attempts for each of the ideas I mentioned above. Also, if you have any more ideas that I didn't include, feel free to submit those anyways. The more the merrier! I will give as much feedback as I can to help convey ideas that I like to help make this process easier. Just as a heads up, I am also in the market for some business cards, and a website should this project go well! Thanks for your help. It will be a pleasure working with you!
