Here is a document with a list of 7 organizations that provide baby carriers to specific caregiver populations for free or a reduced price. Please educate yourself about the organization before applying, aligning yourself, or donating. Some, but not all, are 501(c)3 and thus are able to provide a tax statement for donations.
If you know of other organizations that are similar, please contact me and we can add to this list.
