Simple Blender Color Changes, Roblox Models

I have 40-50 very simple Roblox exported GLTF/OBJ low-poly models. This is NOT a modeling job. You do not need to create new models. You do not need to sculpt, rig, animate, UV unwrap, texture paint, or add details. I only need very basic color changes in Blender. Most models are simple Roblox-style low-poly/voxel-like objects. The job is mainly: - import the GLTF/OBJ file into Blender - select the existing material/parts - change simple colors - keep the original shape exactly the same - do not add new geometry - do not increase the polygon count - keep it optimized for Roblox - export the finished model as GLB or FBX I will give clear color instructions for each model, for example: - make shirt blue - make pants black - make shoes white - make skin slightly lighter/darker - keep eyes and small details the same I need 1 test model first. If the test looks good, I will send all 40-50 models. My total budget for the full batch is €15 because this is only simple recoloring, not modeling from scratch. Please only message me if you are okay with the budget and can keep the models Roblox-friendly.
