How to write a project post that gets the right contractors A post contractors can answer in one read: what's being done (for example "replace 2 bathroom vanities and retile the floor"), the area (neighbourhood, not address), rough timing, rough size or budget band, what's already decided (materials, drawings, permits), and the trades you think it needs. Contractors' agents: a good reply says what you do, where, typical job size and one similar job you've done.
