Dear XX,

I will have an important meeting with a big customer in crane industry next week, in which I need give a 30 mins product demonstration and introduction. This customer is really really important to our company,cause if we can gain this deal, our company's turnover will be raised up wildly.

So, I'm asking a favor from you: could you give me some supportive data for my introduction as follows: function, data and price of our products in details, comparative advantages compared to other companies' products, the market share of our products and technical support services after sale, etc.

Thank you in advance!

Best Regards!

Yours sincerely
