List formalny z prośbą o informacje.

Prosta wersja, gdyż dopiero "ogarniam" zwroty i sposób pisania takowych listów.

Dear Sir or Madam
I am writing to enquire about the cook courses you held in major cities of the country. It would be greatful if you could send me some detailed information.
I would like to know how many hours the course takes and if there is a possibility to have extra lessons. Does the price includes the costs of ingredients?
I am also interested in having more details about weekend courses. Is there any accomodation available for the course attendees?
I would like to ask if you award the partakers any certificate after the course is finished.
I would appreciate a reply at your earliest convenience.
Your faithfully
XYZ

Czy są jeszcze jakieś zwroty, oprócz:
I would like to know
I would like to ask
