Проблема Requesting private assistance on replacing a whole map/minimap. Paying upfront :)

Hello. As the title says, I am interested in this persons' thread here - https://ragemp.pro/threads/ragemp-minimap-change.16936/#post-148479
As you might check, my last reply on the bottom, I just cannot figure it out. I am using redagev3 mode, and I really want to add new mods but this thing is over my head. So again, if you are willing to give me a hand, we can discuss a small tip upfront for your kindness and time waste.
Eventually, you can teach me the way of installing ? AND, maybe, how do you install a car or a cloth via Openv ? Dropping a car inside dlcpacks is easy for me, IF it is downloaded already as dlc.rpf solely and it's plug and play. If the archive contains several files and it's not already a dlc.rpf file solely, I'm dead xd


All the best, and thank you for your time! Either reply here or trough the private messenger.
