dc motor with 89c51

<bold>THIS IS VERY IMPORTANT SO YOU MUST READ PLEASE!</normal>

<italic>dear friends,</italy>

i got a project for ATMEL 89c51
I need to rotate the motor in forward and reverse directions with 2 micro switches.
i am through with all the programming.
i am going to use the ic L293D for supply reversal
ok up to this its all fine with me.....
=============
but the problem is, the motor is of 24 volts and 12AMP CAPACITY.
i cant connect it with L293D ic.

what should i do now....
is there any other discrete H-BRIDGE circuit available or any ic, like l293d , to overcome this problem..?

the application is so simple in the nature but i am stuck with this hardware problem

PLEASE ADVISE, FRIENDS....

RONY.
