I got an offer to come for an interview to take the inter position at the company.
Unfortunate I hade to change time and date they offered me, and I got a replay from the person I will be meeting with yesterday- 'Thatís fine. Please get in touch upon your return and let me know when you are available.'

I want to inform her that I can come to meet her on Wednesday, here is some draft I prepared :
I am writing to ask if you have time to meet with me on September 5th or 6th. Please let me know what time and date suites you the best?

Could you please tell me if it's correct enough or I have to change something! Thank you very much
