if you are talking queen palms they can get quite tall, beyond most of our reaches even with extension saws.
There are many contractors that will do the palm "cleaning" for $7-$10 per tree.
If you have multiple trees you can negotiate a better price. The time to get the seed pods out is before the long spear they are housed in opens. They are very heavy and pointed and fall point first so be careful.
I quit doing ours 4 or 5 years ago....too high and too many. If I had to do it over again I would NEVER put in queen palms they are a maintenance pain in the
