Consultation for implementation with Google Cloud needed

We are looking for a consultation concerning the implementation of Snowplow with Google Cloud for our project.
We have set up the basics but need help with the dataflow service which currently starts more dataflow jobs than we need and thus causes high costs.

Can anyone suggest someone or help us with this? We would prefer someone based in Germany who would be willing to also do this kind of “small” consultation job.

Thanks everyone!
