Reinstall High Sierra macOS does not work (recovery server could not be contacted)

I have a Macbook Pro Mid 2010 which only a few days ago, would not start past the apple logo. So I went on several help threads on the internet, went on recovery mode, ran repair and first aid on my disks, before eventually just deciding to erase my drive. Several of what I had read told me to do that and reinstall macOS afterwards. My macbook, before the issue, ran on Sierra. After erasing the drive, reinstall macOS showed High Sierra. However, everytime I clicked on continue, a “recovery server could not be contacted” prompt would pop up. After this, everytime I power the macbook on, it only showed a folder with a question mark which meant that the macbook did not have a startup disk, however, when I am asked to choose a startup disk on recovery mode, there are no disks to choose from. Also now everytime I try to reinstall macOS, when I click on about Install macOS, the high sierra version shown is 14.0.01. I try to do things on terminal however I do not have the sudo command so what I can do on terminal are limited. Also I dont believe my macbook has an admin user now, I dont know I’m getting very frustrated. I have also tried creating a bootable macos installer USB however i do not have another macbook and have only been doing this on windows computers. That bootable usb probably does not work because when I restart my mac and click on options it shows Internet Recovery as my only option. I also cannot go into normal recovery mode anymore. The only way I can do things on my mac now is by connecting it on my phone’s personal hotspot and going to internet recovery.

Any suggestions or should i just give up and go to the store and pay for way too much money that I dont have. Thank you
