Marketing research for a new yoga business in the European Union

I want to commission a marketing study for a new online yoga store based in the Netherlands but open to all the European Union markets. I want to include: overall market information, segmentation, swot analysis, product research, feasibility, overall market information barriers for entry, pricing strategies, swot.
The most important thing I need to know is if there is enough market, what are the main products on-demand, feasibility and the best countries of EU to sell yoga props.
