Spark AR maker, to build a simple Instagram filter

This simple project will work in
- on back camera
photo a person. (1.jpg)
add another image (ready made) near this person. (2.jpg)
recognizve person face
replace image head with person head (with size & adjustments needed) (3.jpeg)
if there are a few persons on the image, usr can select one face.
on front camera:
take holder picture face
combine with a given image face
Change Opacity of image face (user finger control)
so you can see both faces combine
to open face.

Please bid only if you done similar work
and can send links to filters you did for instgram

This will be first phase in a project, for good Spark artist
with AR JS code writing abilities, one can continue for long

Good luck
and above.
