Review in-app copy and proof-read English to German paywall

We're a small product team building a mobile sleep & wellness app, and we're polishing the German version of a set of paywalls. The copy is already translated — we're looking for a native speakers to review it, refine where needed, and help it sound natural and persuasive to native users. ~17 strings across a dynamically rendered paywall, where the quote/testimonial shown is dependent on the users stated intent of using the app. Please observe that the quotes/testimonials translations must be true in content and tone to not diverge from the actual user testimonial. What strings that are quotes/testimonials will be made clear in the spreadsheet. After accepting the job, we will send over a document with more information, including a spreadsheet where you can directly insert your revised copy. If you think that this job matches your portfolio please feel free to send over an estimate of total hours required to finish this task.
