Resizing images

I need to downsize a collection of images for inclusion in various file formats. The images are currently in their original high resolution sizes and need to be resized to 10% of their original dimensions for integration into documents, spreadsheets and presentations. The resized images also need to be placed into specific cells on an Excel spreadsheet Finally, the downsized images require insertion into selected PowerPoint slides for an upcoming presentation. The images are in JPG, so the freelancer needs the technical expertise to smoothly resize images in various formats. Metadata needs to be preserved through the resizing process. Once resized, the images must be carefully inserted into the designated document, spreadsheet and presentation files while maintaining the original layout and design. Kindly provide your rate and estimated timeline to complete this technical imaging resizing and placement project.
