3D Avatar Based Web Application Required

We would like to have a website simliar to https://lovebookonline.com/ right now its in 2D same conecpt we would like to implement in the 3d along with the existing functionlities of my reference website. Kindly bid me if you have done similar kinds of projects along with your recommendations other pls don't bid and waste your time.

We really like this concept https://wolf3d.io/ and https://fabie.readyplayer.me but not sure the same character can be used in multiple postures which could export for Photo Book? If someone has the solution we can prefer them
