Ask several businesses to price the same work
Pick the tasks, preserve the scope, and invite businesses from your directory. Each one prices the same words, and none of them is added to your project.
Businesses see only the request, the files you share and their own price. They never see each other or your margin. A line left unpriced or excluded is flagged, so it does not look free.
Selecting a price, awarding the work and agreeing the scope are separate steps. Awarding creates a proposed engagement, and the usual scope agreement and credential checks follow.
While you are still pricing the job, you can take a chosen price back and choose another. You can also tell businesses that are waiting when you expect to decide, and nobody is emailed.
