Local design meetups, hackathons and conferences are a great way to find mentors. That's how I met one of my mentors, and that's also how she found hers.

I also wouldn't limit yourself to just designers. Remember that UI/UX design is not just visual design :) I've worked with PMs who are just as good as my design mentors. Even though they lacked design skills, they had years of experience working with designers. Through them I've learned some product strategy, how to collaborate better with developers, research, technical writing, etc.

Mentorship is a two way street. Just the other day, I showed my PM what a user journey is and how to create a user flow using LucidCharts. People in early stage startups usually wear multiple hats. This is your chance of mentoring others too.

His typefaces have been my favourite go-to fonts for most of my design career. We lost a great one.

I use Sketch for wireframing. Sketch + Marvel (for interactive prototyping) = awesomeness

What happens after the website is created? Will you be responsible for managing the website and making sure everything is up-to-date? If not, do you know if anyone in the band knows how to code? If not, I would avoid Jekyll and go with a CMS. I know a lot of bands who use WordPress.com for their websites. It's free, easy to maintain.. it does the job for what your friend needs. Further down the road, you should look into SquareSpace and Bandzoogle if the band wants to have an online store, set up digital downloads, and other features.

I revamped mine last week. Here it is! www.alicephieu.com This was created on WordPress using the Doctype Theme.

Lots of video game designers I know create their visual assets on Flash.

That's true. One of our previous members runs an e-commerce agency that I now work for :)

I've had good and bad experience. It depends on the size of the space and what kind of people work there. My last coworking space had a lot of people and random drop-ins.. it was distracting and not for me. My current coworking space is smaller (6 members) and it's great. Everyone here is an illustrator except for me. It would be nice to have some graphic/web designers here that I can collaborate or share resources with : \
