Hello,
As a fellow camper/backpacker and inventor/problem solver i am very intrigued by your project. After reading your attached proposal i have a few issues with it which is why my price is higher then the others. I have been in manufacturing for a long time doing projects for myself and for others. Very seldom does a design for a new innovative product work flawlessly on the first try, hence your "warranty" I could see this small project taking up a lot of time to get perfected. It would also be very hard at this stage of the process to set a manufacturing price or to source materials. I already have a few ideas in my head as to how I would accomplish this task for you. I can in-vision it being hand held with a thumb actuated mechanism to achieve the spark. I also build and manufacture a lot of different items and I would be able to help you with the construction of the item. As i do have a lot of reservations with doing this type of project on such a fixed budget with a short timeline I still am very interested.
I hope to work with you in the near future,
Mike
