Letter in response to an advertisement

Dear Mrs Anna Richardson.

I have just seen your advertisement in the newspaper and I would like to ask you some questions because I am interested in the job.

Would you mind telling me how many hours a day the job is for? The advertisement said that the work it would be during the summer months but it does not indicate how many days off in a week you have. To conclude I would like to know what the salary per hour is. 

I think I have all requirements that the job requires. I would not mind working some weekends. Moreover dealing with people is my best skill due to some months of experience in other similar jobs that I have had.

Hope to hear from you soon.

Kind Regards.
