Hi there! My name is***** am a computer professional with over 15 years of experience with both Mac and Windows computers, phones, tablets, and printers. It would be my pleasure to assist you with this. I can definitely help you with setting this up. You can create the new accounts by clicking here. Just provide the requested information and follow the prompts on the screen. You can then setup a third party email program, like Outlook or Thunderbird to let you view and respond to messages from each of the accounts. The easiest way to do it on your iPhone is to use the built-in Mail App. If you'll let me know what model your iPhone is and what version of iOS you have I should be able to walk you through it fairly easily.
If you'd like, I can offer the PREMIUM SERVICE of a SECURE REMOTE CONNECTION. This will allow me to see exactly what is happening on your computer and to work on the problem while you watch. This is completely optional. If you do not choose to take this service, I will walk you through a solution step by step here. When we have things working properly on your computer, I can then give you call and walk you through setting it up there, since I can't remotely connect to your iPhone.
