WhatsApp expert needed: restoring an encrypted Google Drive backup + moving to iPhone

Description I need a paid consultation with someone experienced in WhatsApp backups and transfers. I’m non-technical, so I need calm, clear, step-by-step guidance over chat or a call. I’ll do all the steps myself on my own devices. My situation I have a WhatsApp account on a German number. There’s an end-to-end encrypted Google Drive backup of about 20GB holding roughly the last 12 months of messages, photos, videos and voice notes. I have the 64-digit encryption key and full access to the Google account that holds the backup. The original phone is a Samsung Galaxy S23 with a broken USB/charging port, so cable transfers don’t work. My understanding is that restoring the cloud backup doesn’t need that port, since it downloads over Wi-Fi. What I want help with 1. Restoring the encrypted WhatsApp backup from Google Drive onto an Android phone, using the encryption key. 2. Then transferring everything to an iPhone 12 using WhatsApp’s official “move to iPhone” feature. What I need from you • Clear step-by-step instructions I can follow myself. • Patience with a non-technical person. • Honesty about what is and isn’t recoverable. Please tell me • Your experience with WhatsApp encrypted backup restores. • Whether the broken USB port changes anything. • Whether I’ll need a second working Android phone, and any requirements for it. • Your rate and availability. Important I will not share my encryption key or account password to have the work done remotely. I’m hiring for guidance while I operate my own devices. Please don’t apply if you need my credentials.
