Spy Video Recorder - Sales & Marketing - repost

Hello, We are working in mobile application development and website development for more than 5 years. And now we have made some projects for our company and developing android mobile applications. We are selling the free version of android mobile applications very effectively but we are not able to sell for the PRO/paid version of apps. So, we are looking for someone who can do marketing for our PRO/paid version of Android mobile applications so that we can get higher ratings and feedbacks and also increase the number of downloads for our PRO version of apps. Thanks, Best Regards, Gurupritsingh Saini, AppAspect
