All standard hubs and switches support that length of cable and more. The limit is usually given as 100 metres, but you can get away with even longer lengths if the cable is of good quality and is not placed near sources of electrical inteference.
A switch is better than a hub as it is 10 times faster and can prevent or reduce problems due to data collision. An 8-port switch costs roughly Rs.600-1000 depending on the brand.
