Website protection password for every file and directions

Hello all, I need someone that can help me protect my files from being hacked. So now a person can go to [login to view URL] And then he can edit everything and he can change it and see all my information. I dont want that so i want that to be protected. Also the files needs some protection that people cant hack my website. Second my webhosting is doing weird things and i dont know how to fix it. The server is pointing to a ip , and the domain is pointing to a other domain while i heard it has to be pointing to the same ip and i dont know how to change it or whats the best for me. Also i cant upload any files in filemanager or edit them , i need to use filezilla for this while i want just to use file manager. After the job is done i'm paying for the full work. This is only a small job after this i need 1-2 websites to be coded designed and be created full. So i'm not paying upfront , any milestone , any escrow or whatever. I'm paying after the first part is done. then we move on to the second part that is creating 2 websites , for these 2 websites i pay upfront. If you want to work with me PLEASE PM ME I ONLY WORK IF YOU PM ME. Thanks best regards.
