Dear Sir,

Good day.

We're XXX and we'd cooperated with you in XXX field when we're in A company. Now we worked in another company and we want to go on cooperate with you in such field. The way will be the same as before: We response for writting files, and you help to present those files. Pls send us quotation for above work. We hope that you can give us the same price as we're in A company, and it's better if you give us some discount.

Thanks & regards
XXX
