You need a very specific service, you are looking for a professional with certain skills, so you place an ad.
But you get no answers, wrong answers and even mocking reactions.
Your problem? You failed to identify clearly your need (or your client’s need) or wrongly worded your ad.
Next time, consult with a professional in the subject before publishing. It will save time and get the results you are looking for.
This ad was received today, from a major company, they provided all sorts of details and conditions for this job but the only way they’ll get the right service will be to answer a string of questions from professionals and dilettantes alike and will end up wasting a lot of precious time to actually explain what they need precisely.
