You can annouce your availability, and invite contact, in other words advertise once a week on the TER boards.  That's once every 7 days on all of TER, not once a week on each board.

Now if you are touring, you can also post your ad ahead of your visit in addition to your weekly ad.  Just be sure to include the dates of your visit in the subject line.

Hope this helps,
