How do I make two different Google Chrome profiles?

You could follow Google's own instructions on how to set up multiple profiles.

I use this for similar purposes, and it works very well.

You can easily find it on Google. The first link I found from Google says:

For Windows:

1. Create a new folder somewhere to store Google Chrome information for each profile. For example, you can create a folder in your C: directory or another folder, named "chromework" so it will appear as c:\chromework, if in the C: directory. This folder can be anywhere, but in this example, we created the folder in the C: directory.
2. Make a copy of your shortcut for Google Chrome by right-clicking the Google Chrome desktop icon and selecting 'Copy' from the drop-down that appears. Then, right-click your desktop and click Paste from the drop-down menu. Give the copy a separate name (e.g. "Google Chrome Work" or something similar to give you an idea of what browser to use for what purpose).
3. Right-click the new shortcut and select Properties.
4. In the Target field, append "--user-data-dir=[your new directory]" so that the contents of the field reads something like: C:\Documents and Settings\[username]\Local Settings\Application Data\Google\Chrome\Application\chrome.exe" --user-data-dir=c:\chromework. Be sure to include a space between chrome.exe" and --user-data-dir
5. Repeat steps 1-4 for any other profile you'd like to create. Each profile launches a separate instance of Google Chrome.

For Linux:

Start Google Chrome with /opt/google/chrome/google-chrome --user-data-dir=.config/google-chrome/Private
