Golf Club Fitting Hardware / Software / Algorithm Development -- 2

A first contractor for this project was insufficiently skilled, incompetently slow, and then sadly suffered a stroke literally days before it was hoped this project would finally be functional. He is out indefinitely now with essentially nothing delivered and about $10,000 of my money that is apparently forever gone. A second inept contractor totally flopped with some more of my money, and subsequently two more contractors supposedly skilled in this field(s) have also failed to deliver anything useful whatsoever toward this project. I am now in a position where the patent protection period is more than half over for this project with nothing to show for it and uncounted lost opportunities, and essentially back to square one again for finding a suitable contractor(s) to help. Both time and my funds are greatly depleted now and continually becoming even less with each passing day. This is a golf-related project that is needed very badly in order to help stop the clubfitting industry from continuing its longstanding, horrific, and embarrassing performance record and reputation. Some knowledge of and/or interest in golf and the game's future might be a plus but is not required and could actually hurt the project due to so much deeply embedded incorrect knowledge throughout the golf industry. This project comprises first tracking and logging golf club movement data before any part of one's golf swing is even begun (the pre-swing period). While the use of a portable wireless sensor(s) attached to a golf club might at first thought seem most viable for golfer purchase and use, I am still totally open to a video or other type of tracking system if more viable. A selected part(s) of the acquired pre-swing data then needs to be processed through an appropriate algorithm(s) to determine a rotation point location along the length of the club. Help is needed in areas including hardware selection and development and software application and algorithm development. A prototype with which to gather critical foundational testing data for early analysis is first required in the shortest time and at the least expense using off-the-shelf components if possible before the project can proceed further. The most prominent issue to date has been severe drifting when trying to determine golf club position when using an inertial sensor. Different contractors can be considered for hardware and software aspects for instance, so please note if you are a specialist desiring to contribute to any one particular skill described or if you consider yourself qualified to develop multiple aspects of the project. While it still needs editing/amending, a crude requirements document is attached. Even briefly scanning it as desired can lead to some crucial project details and links to investigate if contemplating whether to offer a quote, including a video and other supplemental information that some have said has helped toward understanding the project well. I ask anyone that is interested, willing, and able to skillfully help finally bring any part(s) of what is needed next for this project (apparently slightly ahead of its time) to fruition in as little time and cost as possible to please consider offering a quote and/or contacting me with any questions or comments. With other leading edge projects beyond this one already in early development and continual improvements in this project also expected over time, the potential exists for an enterprising and profitable longer-term relationship if desired. I can consider either project or hourly quotes. Thank you.
