The best place to start in lookibg for an Individual Health Insurance policy in Washington would be to do some online research, and get some quotes. HealthCompare (http://www.healthcompare.com - the company I work with) will provide you with a range of quotes. When you have the quotes, check them to see which ones give you the type of care service you want, and which ones give you a level of copay you can afford. If you are still unsure of which policy to purchase, you should talk to a professional broker or agent - you will then have an idea of the options available, and be able to get more value from them.
I hope this helps, and wish you luck in finding the right plan.
