UK Shopify High Ticket Dropshipping Product Research

I'm starting out and aiming to use Shopify. I am only looking for non-Amazon research (i.e. Google)

Am looking for 10 high ticket ideas, anywhere from £400/500 to £1k/1.5k price range, low seasonality of demand, at least 5k demand searches and above, with existing suppliers who deal with dropshipping companies (low competition) and do returns, and with several (e.g. 6 to 10 existing brands within the market for the product) at least.

Also - types of products which require very little customer interaction would be preferable as well (i.e. low customer support requirement)

I would like you to identify UK suppliers only if possible for this dropshipping model as quality and short shipping times are key for my project.

If this requires more time and effort and you feel the budget is insufficient, please do message me about it.
