Design simple, sleek, highly functional text logo for a mobile app

We are currently developing an image-sharing mobile app with an expected launch date of Jan. 2016. We require a simple, sleek, intuitive logo to be used for our app. The logo must not include any sort of abnormal shaped imagery, and should be mainly text based. Graphical variations within the text are acceptable. Please see logos by brands such as Instagram, Facebook, and Linkdin for examples. Please only offer if you can complete this project within several hours, the sooner the better! I would like to have a logo ready within 3 hours maximum so that we can move forward with the design process. We will require at least 3 working samples to choose from. I will then select the most appropriate one, and we will make any minor necessary modifications. All I ask is that during the design process, you really try to make something very simple and do not over think it! Our philosophy is clean & simple! I will provide the name of the product upon agreement. Thank you in advance for your time.
