If it's for business and you would use it a lot for professional work, I suggest just get a .com domain name (you can get one when you sign up for a website) and then get your custom e-mail so it would be like:
firstname@firstandlastname.com
or
hello@firstandlastname.com
That's how I got my e-mail since all variations of my name at gmail.com is already taken. Moreover, I get a website with it too which I use a lot for professional purposes. If you are curious, I got my custom email, domain, and website using hPage website builder (
https://www.hpage.com) since it's the easiest way for me years ago when I was not yet a tech person.
