High-Resolution Conversion of PowerPoint Slide

I need someone with experience in converting and designing powerpoint slide into TIF format while meeting a high resolution of 1200 DPI. This is for personal use, and it's essential that the TIF conforms to a minimalistic, colorful, and professional style. I invite all freelancers interested to participate as long as they can provide detailed project proposals, showcasing their plan on accomplishing this task. Familiarity with image-format conversion and respect for design nuances are perks. I look forward to viewing your proposals.
