Artist Display website research

I would like to have someone research most functional websites on the internet for displaying children's art that meets these minimum requirements. The websites of interest would need to allow for multiple schools with multiple teachers within a school and each teacher would have multiple students. There would need to be some kind of viewer 'voting' on the website to determine 'winners' for a 'class' and 'school' for given time periods like the week or month. The main page should randomly show off children's artwork from the various schools. Filters to show top artists or top classes or top schools would be helpful. Also to be able to categorize the artwork into categories within a class would also be helpful. Easy updates for the artwork electronic files is a must. The final product would be a list (on Excel) of websites that meet these requirements that are currently 'live' on the web. I am not interested in people to develop this website. I'm looking for existing websites that have this functionality. In the Excel spreadsheet I would like a brief list of additional functions each website found has (i.e. Selling features, email notifications, parents tab, school tab, etc.) I would like to have 25-50 websites that meet this type of criteria with a rating system by the researcher on which ones they believe are the 'best' for the intended purpose of having multiple schools and classes showing off their artwork in 'competitions' that would be evaluated by visitors. I would like this research done in the next 7 days after the award and I will pay a minimum of $40. I will 'tip' work that is done well.
