I am planning to start an educational travel business and in that do I have to pay service tax?

I am a final Year student with the Maharashtra State University and was venturing into Educational travel Business.

Brief Description of the Business:

It will enable the students to go on industrial visit to different industries and different parts of the country.

Thus in this case I wanted to understand the implication of service tax and what are the details needed to be made sure we submit the right documents to prove that we are only doing educational trips.

Also what is the rate of service tax?

Can my neighbor operate a commercial business on residential lot?

My neighbor has an easement across my driveway to access his home. His property is zoned as residential and is 3/2 home. He runs a big tree business and parks 3-5 huge trucks there each night and drives them over the easement each day. His workers meet there every morning and has place a huge 18 wheeler trailer on the lot for storage. Is this legal? how do I address this locally?
