Gerontology Paper Edit & Source Check

I have a nine-page university paper in gerontology that explores homosexuality in older age and I need more than a spell-check. Please help me tighten the logical flow, make sure every argument builds smoothly toward the conclusion, and verify that the cited page numbers and quotations line up with the literature. The spot-checks should cover all references evenly, not just the major studies. Your deliverable is a polished final version of the text plus a brief summary of the most important adjustments you made; I do not need a full set of tracked changes. When you reply, let me know your per-page rate and any relevant experience you have working with gerontology or related social science topics. I look forward to collaborating with you. The seminar paper must be written in German.
