I sell and design tombstones, our revenue is kinda fixed since only so many people die.

I've worked for the same company for over ten years. I started as a green maintainer. I've grown within the business and got asked if I wanted to take over the business. I said yes. You may, or may not know that only so many people die yearly, of those people only a certain percentage get buried. Depending on where you live the percentages could be very different. Now I'm thinking about how I could increase the revenue, what would your take be on this?Some background information:We design and produce tombstones. We do have a small stock of tombstones that could be placed immediately, but the delivery time is generally between 8 - 12 weeks. The average price of a tombstone is around €2200,00. We got a conversion rate of around 90%. We get around 2 - 4 customers a week. We also manage three local cemeteries that produce revenue. I've got two full-time colleagues and 10 colleagues who only work on Saturday responsible for the green maintenance. see hubwealthy.com/wealthy
