[Koha] Vendor Question

Hello, Our School District is interested in at least taking a look at KOHA, but we can't seem to find a pay vendor that would support it. I called liblime.com today and was unceremoniously told that we are "too small" a School District for them to support. Now we have 2700 students and 4 -15,000 Circulation Libraries and are looking to possibly switch from "Follett" Winnebago to another platform.
