Благодарственное письмо

[psyhea]

Здравствуйте,

Помогите, владеющие английским языком, пожалуйста, составить благодарственное письмо директору фирмы, которого надо поблагодарить за прием и за советы, а также проинформировать об открытии нового магазина оптики.

Вот первоначальный набросок:

Dear M P,
I would like to sincerely thank you for the time that you spent with me last August while my last travel to Milan, giving me a precious piece of advice for organization and running the business.
I am very pleased to inform you that our new brand store “O” began its activity the 28th October. The innovative character of this brand consists in new approach: to propose more services to our clients which complement the ordinary sales of optical devices: eyes care advice with eye massage and food recipes, guaranty extension to satisfy the client long after his first visit and thus to provide the continuous health visual care.
I look forward to hearing from you in the near future.
Yours sincerely,

Пожалуйста, укажите на мои ошибки, так как английский совсем атрофировался.
