Mutation of land procedure

Hi,

I want to do the mutation of my land in which , we have built our home.

Our home is in private society. Some of our neighbhood already done with the mutation.

Our khasra number is 998.

My name is present in Khatauni in the gov website but not in bhulekh.

For the mutation, I have approached one lawyer. We have given all the required information and he already taken 7000 Rs. from us.  Now around 2 years are over, still that lawyer is not able to do mutation and not ready to return the money also.
He is again asking for more money. Everytime he ask for some more money and time.

And after taking the money and time, he is failed to do the mutation without any statisfied reason.

I have three questions:-

-How much time and money is required to do the mutation of the land?

- What is the procedure to do the mutation?

- I am suffered a lot from this laywer, he is making us fool from past 2 years.What action I can take against him?

Please reply to the above three questions.

Thanks in advance.
