I live in Vancouver Washington. Is there any jobs open for 13-14 year olds?
You might try looking on care.com I did a search for jobs in your area and found a tutor needed for a 7 year old, and also a babysitter is needed. Both of these are listed on care.com. Click the link to see them. http://www.jobs2careers.com/Jobs/q-Jobs-For-15-Year-Olds-l-Vancouver-WA/
the only problem is that for care.com you have to make an account which says you must be legally allowed to work (i.e. 18 years old) so that makes half of the jobs on there irrelevant...
