Earlier quoted context omitted.
Well then how am I going to figure out whether or not you can code? The only thing I can think of is an expensive two week trial period which doesn't make sense since I feel that most programmers will either submit work or submit to a pop quiz.
Good developers cost, what, $120K-150K/year? If a two week trial period is "expensive" to you, you don't have the budget for someone in that pay range.
A programmers who is currently employed but thinking about moving on probably won't agree to a two-week trial period because of the substantial risk that they get rejected afterwards and end up unemployed. That makes the trial period expensive to him. In turn, it makes it expensive to the employer as well, because you'll filter out good people.
