I would tell you this man as an inspired guy myself. Do LOTS of Front Squats and Back Squats. This will give you the strength and probably 80% of the positional strength needed to clean big. Drop the clean pulls. Do real cleans. Diet and cardio and lifting together will help you with dropping weight. The key is to keep lifting heavy, but you don't need to go crazy heavy every session.
I would say have a long term goal and a short term goal.
Make your first goal to properly clean 60kg. Then 70kg. And a few years from now, who knows maybe you can get over 200kg in a clean. If ALL you want to do is clean big. Then start cleaning 2-3x a week. Don't do clean pulls, don't do snatches, don't do jerks.
Front Squat strength will carry over to a big clean. General rule of thumb is if you can FS it for 3 good reps, you have the strength needed to clean it.
I would go to a weightlifting club as well to learn the technique. While we can tell you things on the forum, when it comes to the Oly lifts, nothing like having a coach. Even if it's once every 2 weeks it'll make a difference.
