but I can charge them to reference it in their bibliography of their dba, scheme of works?

Good luck trying to get that one through. Way to kill the golden goose if you do. Having to pay to reference works in a bibliography would kill research, especially that done at PhD level. Can you imagine a PhD student having to fork out for the hundreds of texts that they reference in their bibliography out of their student loan? What about all the sites that are meant to be published with reference to other sites in the area? Either sites would be published in isolation, making the work undertaken largely meaningless or the cost of the work would go through the roof and development would not go ahead. Where then would be your nice little earner sites? You would ensure that you had no more work. It's a bloody stupid idea and it is a good job that you cannot do this.
