For low cost safeties, there is this list:

However, if you make NMF, your list gets larger:

Because most large competitive (as opposed to automatic-for-stats) scholarships are not very transparent on how difficult they are to get beyond any minimum requirements, they should generally be considered as reaches. Here are some (other than in the NMF list which includes both automatic-for-stats and competitive scholarships):

If they are unwilling to tell you what their contribution limit is (perhaps due to not wanting to admit having blown the budget on your older siblings), then assume that they will be able to contribute $0 when making your list (particularly with safeties). You can reasonably expect to self-fund at most $5,500 (federal direct loan) plus a few thousand dollars per year of work earnings.
