Convert some PPT diagrams into high res images

I'm looking for someone to convert a few PPT diagrams into high res images. There will be 4 diagrams in total, and my preference is for the images to be optimized for web use. I trust the freelancer's judgment when it comes to the color and style of the images, though would like them to be compatible with a website that is already designed (which I will share). I'm looking for someone with existing know-how who can quickly and efficiently convert my diagrams. If you think you'd be a good fit for this project, let me know and I look forward to working with you!
