Alwar , in Rajasthan

I own a residential plot of 150 sq. yds. in the city
of Alwar , in Rajasthan, in an area called the Budh Vihar Ext.
I would like to lease a corner of my property for the
pad of a tower.
Who are the agents to contact?
Can I bypass the agents and contact the companies
directly?
What kind of income can I expect?
