I used to be in classified advetising for 15 years and mostly help wanted.
You want to make your title your may draw:
Housekeeper
Part time Sat & Sundays Seasonal starting in November and ending in December for a local Bed and Breakfast. Must be flexible and availablability on weekends is a must, if you cannot work weekends please do not apply. You will be responsible for: (here you put some responsibilities). Call us on ____-_____ at______ or e-mail us at ________ for an interview.Salary is comensurate with experience.
This is a simple ad with the specifics, you know if they call after, before or not within the hours that you have in your ad they where not following directions if you want them to have experience state this in the ad. The title can be whatever you are hiring for-you can mention that its at a B & B. sometimes you have to spend a little more, but its worth it to get the quality people you want and always always place your ad on Sundays but NOT ON MONDAYS, Wed and maybe Fridays...People don't look at want ads on Mondays they look on Sundays and call them on Mondays, go on interviews on Mondays and maybe Tuesdays and start looking again on Wed and Thursdays.
Hope this helped or hope its not too late for the ad..
