Cut out the signature in PNG

In the archives Sources_1 and _2, there are high-resolution photos.

You need to cut out the signature drawing and make it with a transparent background in PNG.

In the Archive "Examples" — the resolution of which is sufficient and the quality of which is adequate, less than which is already undesirable.

Detailed instructions are in the attached text file "Instructions_Signatures".

I haven't counted the total number of signatures - about five hundred. I am willing to pay $0.1 per signature, totaling $50.

It is not essential to use my sources - this seemed to me the most straightforward way to solve the task. If there are signatures with the same quality and liveliness as in the Examples - I can accept them. For starters, five hundred signatures are enough for me.

Generators are not suitable - naturalness and Cyrillic are needed.

To start working, you can send your implementation of a couple of signatures - and after that, do everything else.

The first four example files are made from the first four signatures of the first source file - they do not need to be made - but they are good for orientation regarding quality and what I need.
