I would like to know several ideas or tips for well organizing a
private sale of goods at home. This is NOT a garage sale, because all
items to be sold are new sport clothes and most of the assistants are
women (ages from 20 to 50). I imagine that exist many things to be
taken into account to make it a successful event!

Hello,

I believe that your question will require more time
and effort than the average amount of time and effort associated
with this price.  Here is a link to guidelines about pricing

Clean up and straighten up the house.  A messy house reflects on the
quality of the goods.
Arrange to have the clothes on hangers and hanging.  Maybe racks
borrowed from a thrift store for the day.
Price tags, not just a price on the racks.  Items may not be returned
to the proper rack.  And no running around asking:  "What does this
cost?"
Staff organized: responsible for an area; responsible for keeping
track of items being tried on, and for keeping racks tidy.
One person only minding the till, or each till.  IF you take checks,
advice about controlling that they are properly  completed; receipts;
change to start the day.

Do you have to worry about sales tax?  I don't know, but you should,
and then have a table for figuring it.

If you want to clear out everything at the end  - 20 % off, or
whatever - announce it loud and clear and set up a sign  - but don't
let anybody find it early.

Powder room,  trying-on space.

Something to drink?  Place to leave cups/glasses while looking at
clothes, and staff should be polite about asking people to use it.

First choice for the direct neighbors?  Even a 10% discount if they
will be bothered by the traffic?

An inventory of items at least by price for a control of sales and what's left.
