Help me please.......................?

please help me to draft this. i am only 18 . and english is not my base language.

Why you need reference ? do you have any doubt about my photography?
Most of my students are diffidence kid. Caz my father was a renowned army officer as well business man. I am a system analyst and I got my graduation from uk on computing.
Money is not a big fact to me caz, I am a full time job and family business. Why you thing negatively? Photography is my passion not my profession. I felt interest caz, your kid is only 5. and it鈥檚 a perfect age for photography. Plz, don鈥檛 thing all Indian are poor.
Now, I don鈥檛 like to teach your kid. Thanks for the understanding.

May i ask why you need a reference? Why exactly do you have any reason to doubt my photography?
(I'm not sure what diffidence is)
My father was a renowned army officer as well as a business man
I'm a system analyst and graduated from the UK in computing. Money is not an issue to me as i have a full time job in my family business.
i don't understand why you are behaving so negative?
Photography is my passion not my profession, i was only interested because your child is only 5 years of age and i believe it is the perfect age to learn photography.
Please don't think all Indians are poor.
Because of our misunderstanding i do not wish to teach your child anymore.
thank you for understanding.

If you're using this to get a photography job, I would take out the first part. It's a normal thing for people to ask for references if they don't know your work. This person is about to pay you to do a job and they want to know that you are professional. The last part will also hurt your chances of getting the job. Cut out "why you think negatively". Also cut out the last three sentences "Pls, don't thing all Indian are poor. Now, I don't like to teach your kid. Thanks for understanding"

The way this is written sounds confrontational and no one will hire you if you present yourself in this light. Try something like this instead:

"Photography is may passion. I'm interested in photographing your child because of his age. Young children are very expressive and make good subjects for photos. I can show you some of my work so you'll know that I know what I'm doing. I am working on developing a photography business and don't currently have clients for you to contact but my work will stand for itself. I would like to have a conversation with you about your needs and how you would like your child to be portrayed."

Good luck to you.
