I would first select a company name related to your niche. Select a keyword rich domain.
Secondly a .com is much more valuable than a .me so if you are planning to have a commercial website it's is better to stick with .com.
I have a long last name which people find complicated too.
I just shortened it to the last 3 letters "Sch". It really depends on what you want. I'd just try and stick to something you think would be easy to remember.
I would think your last name would be the best option for you. Not only is it short, but it's memorable. Using your name is also a great method of getting your name out there.
