Wondering if i should offer free nail clipping for the dogs in my area ?

ok guys i work at a rescue and i usually clip the dogs nails in the centre as it cuts back on vet costs i have also been clipping my dogs nails for years , the last few months while out on walks i have been speaking to other dogs owners and the price of nail clipping has came up alot as it is �30 just to see the vets in our area and then further priced for simple things like nail clipping, and it seems as tho a lot of people are just leaving there dgs nails to get unbearably long because of the price. so my question is should i advertise locally to clip dogs nails for free and to show owners how to do it correctly, i know im not doing a lot really and people should pay for the care of there dog if they choose to have one but its the dogs that are suffering unnecessarily for the owners to save a few pennies.. do you think me doing this would be a good thing or just causing people to take there dogs to the vet less , im trying to weigh out the pros and cons as i have always liked to help animals as much as possible so what is your opinion ?
