Replace the mannequin

Hi, are you sure that maya lt support these features? i cant find options to copy skin weights in maya lt

the meshes are almost identical, like same pose, same size, same amount of fingers…

also i feel like im not far from getting it right, f.e. when selecting the head bone and rotate it, it deforms pretty well,
the problem is feets and hands, f.e. some vertices on the feet just stay in place when rotating the knee bone

is this a huge workload? what would be a reasonable price if i wanted to outsource this work to someone experienced?
what would be the best place to find freelance people helping me out on this?

best regards
