Improve a powerpoint slides with correction of english contents

This platform is to benefit Sport Coaches of any sport and people that are searching of Sport activities, the platform (I would suggest to have a look) offer many functions that for the user is easier to find a sport to practice through the filter and see the testimonial of the other people that have used this coach , plus is possible to send message to the coach directly through the platform as well to call directly .

For the coaches has the possibility to build his profile in the way that is similar to a basic webpage , well I say like this for the functionality , it has many information that the coach can add , everything for them to have the best exposure possible , in the Powerpoint I need to explain all the benefit mainly for the coaches , this document will be send to personal trainer of any kind of sport, to fitness studios , club center ect. the reason is explain at glance of what is about .

I need to fix the English contents as well have a better understanding of the slides, in the document there are the majority of the information , but please use your creativity and make use an easy language , not formal . www.sportandsalud.com

I believe I did a good Job , but I need someone more professional to make it better
