**THIS IS NOT A BID, JUST AN ICE BREAKER**
Going by your entire project description, I can see you are beffled with huge amount of non competitive bids. I would try my best to steer away from that and be concise.
Regarding Biometrics, I am aware of Face recognition, fingerprint and iris scan method of authentication and have worked on fingerprint auth, not on a direct hardware level, but with Google APIs on supported Android devices.
On geolocation front, I have worked extensively on location tracking nd have built few apps around this area. Following your protocol, I am not going to showcase them here.
Now, the actual project you are taking about. The thing you have mentioned is not a plain task and people are trying hard to get this done. 3D modelling a human to map and fit garments is an challenging task, and if someone gets it right he is sure going to make millions since this is going to change the future of e commerce industry. There have been attempts to it, nothing has came out yet commercially.
If I have to do it, I would need a team having expertise in AI, ML and modelling than anything else. It would need building a ML model, train it with enormous data in form of multiple people in different outfits. I hope you can imagine the permutations and combination needed to train the model. Then combining AI and ML you proceed to build the 3D rendering of the model.
If you have money, this is not the place to lookout.
