Hi Sir I called your company and talked to your clerk and told her about the working hours that is possible for me .She told me you must talk to manager about this issue. So I'm writing to you to inform you. All of weekdays except Thursday I can be present at the company. This is your text so here is some of the things that you may fix 1- Use a formal language in this kind of messages or letters so you’d better start with : Dear Sir instead of Hi sir it’s more formal and respectful 2-i called your company and talked to your clerk about days and hours that I’ll be available to work ,but she pointed out that I should speak with you Sir about this issue . So I’m writing to inform you about my availability to work , I’m available for the whole week except for Thursdays Thank you 3-If you need a closing you can use : Yours faithfully YOUR NAME

Dear Sir (Hi is too informal when speaking to an employer) With reference to the position of ........................, I rang your company and was informed that I should contact you regarding the hours I would be available for work. I am available every weekday except Thursday.
