There are 30-size electrics. They could probably carry that weight. They are of course more expensive. Also the safety issues about bigger helis should be taken more seriously. A mini electric might cut you and beat you up but probably not kill you. A bigger heli might very well cause fatal accidents.
If you are a beginner I M H O it might be a good idea to learn flying on a mini before you go to something bigger. If you can master a mini you will save yourself a lot of crashes and problems when you start carrying expensive cameras or other stuff on a big machine.
