What are these Japanese characters?

I am very new to the language and I am trying to figure out how to say this word (someone's last name) in the photo, as well as type it out. I'm wondering if someone can help me by:

1) Typing out the word in English so I know how to properly pronounce it.

2) Typing out the word in Katakana so I can copy it on my computer and use it in future online messages to this person. (I've been able to find some of the keyboard characters "エ ル セ ー", but am having trouble finding the others)

Thanks so much.

I can't think of anything that would mean anything, but when looking up in DuckDuckGo, it seems to show my quite a lot of shoes and some rapper I think?
