Teleprompter software for windows, please suggest a good one

[kadari]

Hi,
I've bought a mobile holder stick, and connected it to my desk.
I've placed my mobile on it.
I've positioned it in the front of my 27'' screen, and if I divided my screen to 3 horizontal parts, then it is about in the top part of the screen.
I am setting in my chair and the mobile will record me speaking for my head and half of my chest.
After trying many trials I've found that I do stop from time to time and the words run away from my mind.
I've searched for best practices for video scripts and after many things tried, I've found someone suggested using a teleprompter.
I've watched a lot of YouTube videos about it and really can not afford buying a teleprompter as it is costing a fortune in my local currency.
So I thought about if there is a software that can do the job of the hardware teleprompter.
I will run the software on my screen, and mobile recording in the front of the screen, and I am setting in my chair about 60 or 75 cm away from mobile on my desk.
So what would be the best software that may support this scenario?
Also, is there any way to let other software like word or a like do the teleprompter job?
What let me thought about using my screen is to use it as a way of lighting instead of buying a ring light and place it behind my mobile. and also this way I will have a fixed setup.
I am also have the Logitech c920 web cam with small tripod for it, so I may use it instead of the mobile, or place it inside the mobile holder stack.
But always the screen will be used.
So what software I may use to do the teleprompter part.
I will do it almost daily as it is an educational based contents so there are a lot of curriculums to go through because screen capturing is not working well as students or audience did not feel interactive and many requested to see a normal human being instead of screen or presentation associated with sound.
This was the main thoughts about go to the teleprompter way.
Please advise.
