Add 1 member to my shared folders, instead of granting a license.

I have to say that as a small business owner that has used and supported Dropbox for years, I am very frustrated and disappointed that there is no option to add just 1 team member to my shared folder who can easily upload documents. I have a VA that creates all of my graphics and need to be able to upload all of those to my shared folder. The only solutions that I have been given is to do the "team" membership which is for 3 people and instead of costing me $12/mo. which I pay now for my Plus membership, I would now have to pay a minimum of $45/mo.(if paying for the whole year, it is more month to month) OR I could use the "request folder" option... which will make my life a nightmare. We have about 15 folders. I would need to grant a request to each one and it expires after 10 days. It would not be difficult to add an add on option for 1 team member. I would be happy to pay an additional $15-18/mo. to add on just 1 person. I feel like this would support the smaller and growing businesses and make it a more doable option.
