Catering for locals

My mother did extensive remodeling and an extension on her house including landscaping on Oahu. It took over two years from the planning, permit, inside and outside work. She is planning to throw a party for all those who contributed and their families over the summer. I will be visiting then, so I said of course I will help, but looking online there are so many options and not being local myself and my widow mother not eating out a lot, I would really love ideas:

A: a local catering that local families would love to eat from, she’s paying! No budget really, she wants it to be nice for them to come and show their families what they worked on all this time, or what they worked on a year ago, how it turned out (beautifully, she’s so happy). Bonus points for companies that can also source rentals (tables, chairs, etc) or,

B: a local party planner with ideas on all this. Online what I’ve seen are mostly wedding specialists pics of the venues, etc., we have the venue, it’s everything else we need. I may be reaching for the stars thinking this type of consultant exists for a party of 40-60 ppl, but maybe you all know someone.

Mahalo and many thanks for any ideas in advance 🙏
