It can't be stressed enough that you need to fix whatever is causing it to run lean before any tuning is done. It should not be running lean on the stock tune, there is a mechanical problem, most likely MAF or O2 sensor. Once it is running right I would bring it to a reputable tuner (Like Don) rather than trying to do it yourself. You can do serious damage if you make a mistake. I thought he charged around $300 for a street tune but double check with him.
