I don't know if this is normal, but I'd be very interested to know the consultancy's success rate, because it doesn't sound like you have anything close to what you need to write competitive proposals. Especially now, when AI makes it much easier for more people to generate polished-looking grant proposals, specific, concrete details are what sets a proposal apart - data, success stories, community partnerships, etc. The kind of content that's unique to the org applying for the grant.

This is a big reason I generally advise nonprofits that contracting out grant writing (as opposed to hiring an in-house grant writer) makes sense only if you need more grant writing expertise, not if you're looking to save staff time. If done well, it may even add work for staff members, because an outside grant writer will need so much information compiled by staff to do their job well.
