Frankly speaking, I have not worked on a business plan for an actual business. But, for one of my classes in school, I wrote a business plan as part of our final project, and it was later adopted by the Professor for use in his course materials. So I guess you could say I am a rather concise writer. I am attaching it via private message. In terms of the technology lifestyle goods market (phone, ipod cases etc), I have worked for a company in Hong Kong briefly, that imports and distributes such goods, so I am quite well-acquainted with the jargons that are often used in this industry. As long as you can provide me with information of how you wish to run this business, I can definitely provide good writing with clarity, as well as suggest some points you can incorporate into your operations plan and marketing strategy. I can also format and make the plan look great, in case you want to use the plan for pitching as well! Cheers!
