I would like to learn gujarati or hindi

Hello, is there anybody who could teach me some gujarati or hindi?  I plan to go to India this year.  I can teach you English, French or Spanish.  I would also like to learn the culture of this huge country....I probably will go to Gujarat.  If somebody is from this part of India, could you tell me if it is better for me to learn gujarati or hindi?  With hindi, will I be able to talk to the people in the street? Thank you.
