If you are talking about this particular Indian team then yes they willl use PSLV but other teams may devlop there own rocket.
Yes and ISRO does not have any experience in making rovers infact the the rover which ISRO will send in 2017 to moon by Chandrayaan 2 will be ready by 2016 so in this field they wont be getting much help.
It is not that much easy as you are making it otherwise so many teams from Germany,Korea,China and Japan wouldnt have left the competition in the first place.
That would be very nice if some rich buisnessman funds it but i doubt it.
LOL,you edited your post didnt you???
