Custom Charity Website

Hi there

I need to create a website for a “charity organisation”, whereby charities and suppliers (businesses) register on the website.

When a charity registers, it needs to be able to display a list of it’s “requirements”, such as monthly shopping lists, electricity accounts, clothing, food and so on.

A supplier must also be able to register (business/supplier) – which will be advertised on the site =- and then also listed as suppliers for the charity requirements.

for example, CharityABC would list a shopping list for what they need from Supplier: Bob’s Furniture – so when someone wants to donate funds for furniture – they can see the preferred supplier is Bob’s furniture

Does anyone perhaps know of such a plugin or theme which I could use to achieve this please?

Thank you
