That's truly great. I was doing the something similar 30 years ago. I hear what Valerie says, but if you are providing advice and design services where there wouldn't have been any then that isn't devaluing the paid work. I took a pay cut to work as a Senior Graphic designer for a Design Charity were some of my time was dedicated to free advice to unfunded community groups. Some of the profit from paid work went towards paying for this as well as outside funding for that part of the service. I also organised and supervised regular student work placements who would gain valuable work experience providing a no cost design service for those groups following on from that initial advice.
