Hi there!
I'm Pranav, from India.
Well, first of all your English is pretty decent. I didn't even realize you were not a native English speaker until I read the last line :)
I've just gone through the attached schematic and I can assemble the circuit on a breadboard for you. However, my bid amount doesn't include the components, so you will have to buy them and send them to me. You could buy them off mouser and get them delivered at my place.
It will take me an hour or so to assemble everything on the breadboard and make the video for you.
My bid amount includes my time to assemble the project on a breadboard, and to troubleshoot if any errors are apparent.
I do not need any security amount from you as you already have a review, and you can see my profile to ascertain my honesty.
I hope we can have a pleasant relation.
With warm regards,
Pranav
