Serving an individual you're suing by serving the receptionist at his place of business would not be effective. See RCW 4.28.080. You need to serve the defendant personally, or leave a copy of the summons and complaint with a person of suitable age and discretion at his personal residence - assuming you know where that is. Otherwise, you need to attempt to have him served several times at various times during various days, and if unsuccessful, you can ask the court to allow you to serve him by publication (i.e. publishing the summons in a newspaper). However, that can run you several hundred dollars. Finally, your summons and complaint need to provide the Defendant a place to serve you his Notice of Appearance of Answer. If you fail to do this and take a default judgment, it would be subject to a very quick and routine vacation. It sounds like you either need to file your lawsuit in small claims court, or wait until you have the funds to hire an attorney and proceed appropriately.
