Hi Isabel,
as far as my opinion is concerned, it is a good idea, but there are few points to be considered before that -
# Firstly you should be awared of what exactly HUMAN RESOURCE is , I am saying this as you stated that you are new into this field.
# For appraisal system , you really need to know everything about it, because you are going to sell it, not using for your company..
# For Performance Appraisal, you should know everything about T & D also, as it will help you to compare and identify the performance......
With all these, this is a nice idea, you can go for it...
On your question for this in our country..
Yes we have many top placement companies who are selling almost all the functions to many major companies....
