I am looking for someone who could write a letter (approx 300-500 Word ) introducing our company to other companies. We are based in the UK and are trying to open communications with a set list of companies in Singapore. We want to advertise or services and start to build relationships. We are looking for creative writing and introduction to potential clients which will also be translated into singaporean chinese. All materials must be unique and not copied from somewhere else. Your English needs to be 100% perfect and it needs to sound professional. We expect 100% professionalism. Letter needs to be written in British English. Once price of works is agreed I will send over my company details and further instruction, this isn't a huge job so please price accordingly. All the best
