Help completing one blender and two Marvelous Designer outfit files

[Gekko200000]

Hello everyone! I'm hoping someone will be able to help me complete or convert three outfit files. The modder I hired to make them has unfortunately needed to drop the project due to covid/arthritis complications and needing to focus on other jobs. I admittedly know nothing about modeling or modding (other than how to install the completed mods), but the files should be fairly finished. According to my previous modder, "first outfit is a blender file as [they] had started optimizing it, the rest is Marvelous Designer files.". They've been working on it as much as they could for the last year, so I'd love to see these finally finished. Please message me if interested, any help would be appriciated!
