It is possible we could require ten posts as a prerequisite for making requests, but +10 rep seems pretty high. Unless you are a prolific uploader, it's actually pretty hard to get your first ten rep points.
That's true enough, I suppose.
However, I go through the request forum quite frequently to see if I can help, and my observation is, that all too often neither post count nor rep requirements will help.
What would be needed most often is a basic sense of civility, some english lessons, and a functioning pair of eyes, to put it bluntly.
