Tub Cat is sorry to hear about your grandmother.
What you are trying to achieve does have its merit however there are weaknesses to resteem services which make them a real challenge. I'll give you a run-down of what these are:
- Resteem services are primarily used by low rep accounts
- The people that are likely to follow resteem services are also low rep accounts
- Resteem services don't monitor how many of their followers are still active - meaning it is quite possible for a large percentage of their followers to be inactive
- High rep accounts i.e. the ones with real influence, do not follow resteem accounts or use them
- Resteem services have a broad spectrum of followers, meaning that the content being resteemed needs to be attractive to a broad spectrum of people for the author to gain any benefit from the service
As you can see, there are a lot of challenges with these services. And this is why I encouraged you to build a reasonable following and reputation before advertising your service. You want highly active, high value and engaged followers to resteem good quality posts to.
And it is very honourable that you don't want to resteem spam posts. This is definitely a positive aspect of having a human behind your service.
If you can deal with the challenges listed above, then all the power to you.
Tub Cat is not hating on your service, he just doesn't like spam comments.
