You have to think about how to differentiate yourself better. Stating SSAS and SSIS does not do that, and it does not explain the value, you create.

Selling Data Warehouses is often a hard sell, as it usually is expensive, and the customer does not understand the value, you create; management always get their answers even it means some poor controller has to work late to transform a csv-dump from somewhere into actionable knowledge.

Define the business problems, you solve; what are your use cases? And sexify your delivery by doing mockups in a nice frontend tool. Businesses buy from the looks of your output - not from the design of your data model (unless you sell to IT people). And try to combine your technologies into products, that companies buy off the shelf. Again - you’re selling the output, and people don’t want to understand the technology, if they can avoid it. (Unlike IT, where they will ask about maintenance, scalability, etc. So make sure you cover that too).

To get started, do some maintenance work with existing applications on a consulting basis to understand customer needs and make a bit of money.

Good luck! Feel free to set up a call, if you want to discuss things further.
