all he needs to do is rotate his model around the origin point in edit mode so it stands up. his main problem comes from parenting the rig to the model before he scaled it. delete the rig you have and all associated bones. go into vertex groups, and delete all the vertex groups for each item of clothing and the body and face.
now re add a new meta rig. scale it to fit your model IN EDIT MODE. then STILL IN EDIT MODE move the individual bones into position in the mesh, finger bones into fingers leg bones into legs etc. now once that is complete go into object mode.
press space , type rigify into the space bar and select generate rig. once the rig is on the model move the human meta rig to a deserted layer and then select all the body parts, then select your rigify rig ( the one made of circles and stuff thats in the same layer as your model, and should be the same size as your model) press control P select from the menu " with automatic weights" check that it deforms nicely by selecting the rig and going into pose mode and moving bits around. if it deforms badly (it will deform badly) go into vertex paint mode and adjust the paint weights for the bits that deform wrongly.
rigging will take you about 5-10 minutes. weight painting will have you back here on the forum scratching your head after an hour.
still need weight painting a little bit.
