What kind of magnets could pick up 100kg or more? And where would one get them? (I dont know a lot about particular magnets so I cant go into specifics)

The strength of a magnet is usually given in Teslas or Gauss (both of which measure the magnetic field strength on the surface of the magnet). A 1-inch cubical magnet with a 1 Tesla field strength might be able to lift 5 kilograms of iron (just a guess based on my experience with neodymium magnets). So, if you could attach 20 such magnets to your object, they could probably lift 100 kg.
Alternatively, you can use an electromagnet. These are much more complicated, requiring hundreds of coils of insulated wire and an electricity source.

Get neodynium magnets, they are the strongest type of permanent magnets.
I'm sure somebody on Ebay will have them, you can find some in old hard drives as well.

You wouldprobably need an electro magnet.

Please see the link below for a neodymium magnet. It can hold over 600 pounds of force for about 60 dollars I think.
