I need my corporate powerpoint presentation improving

Kind of design: Full presentation Number of slides needed: 15 Ideas for the visual style: Needs to be clean and crisp Preferred colors: I have corporate colours already included in presentation Extra notes: I have 15 slides of powerpoint I am currently using in sales presentations. They are example slides but good versions of the type of slides I use on a daily basis. I would like these 15 slides improving with elements such as (but not limited to) inserting corporate logos (which I have), adding animation, standardising, making more eye catching, adding phase in / phase outs. Essentially I am looking for a templates for some text heavy slides, some graphic heavy slides and some logo heavy slides which I can then tailor easily myself with bespoke content for the companies I am presenting to. Ideally I would want someone to take my slides, make suggested improvements and then send them back to me (can be in PDF format), I give feedback and then this feedback is incorporated. Looking to get this job done in the next 7 days
