If you are talking about Sugar Hill Works , they might be on winter break right now as well. In such case they are by appointment only. So call or email for location details and estimates.
They are in Harlem near 147th Street and St. Nicholas Avenue near the A,B, C,D trains. They messenger and mail stuff, but talking to them is an education. They are a hands on “mom and pop” operation, in a home office not a store front.
You can tell them I recommended them to you.
Peace and Good Luck,
