I would really like to help you be successful. I have a degree in marketing and have consulting experience that would be valuable. I also am not currently working a full time job so I would be able to dedicate the time you need for this to be successful.
My plan would start with the 4 P's of Marketing. First would be the Product. We would analyze your competitors to figure out how we should position your product in the market. Next would be to develop the Price of the product based on the position in the market that you choose. You don't want to be overpriced but yet you want to make a profit. Next would be the Place(distribution)of the product such as android market. Finally would be the Promotion of your product through a variety of cost effective resources such as free social media, articles, and press releases.
After we have this done I would then create an implementation plan for you to follow that would help you get through all of the steps 1 by 1.
The reason you should pick me is because I have the skills, knowledge, and the will power to see to it that you succeed. If you have any questions or would like to discuss this further then feel free to contact me. Thanks
