Without wading through 8 pages of replies here's my few thoughts; the prices are too high for what they are in all fairness, though they are well made and finished with obviously good moulds made and used, with good processing techniques to remove air voids etc it's still just concrete, as has been said there seems no variation on the basic design compared to a plastic clock, and if put side by side with one, little to show it's actually concrete for those looking at it away from the website.
One of the biggest reasons why concrete items have become increasingly popular is because they are polished and because they are made from concrete with aggregate, have the stone component visible with all the variations of that with glass additions and all manner of other quirks that are visible, thus giving you a terrazo effect, while yours are just plain grey.
Now obviously having them polished will add cost and time, but it is doable on a home scale with the right items.
The clock faces themselves apart from the slightly raised sections have no obvious marker for the hours. Now I can understand that for some this is desirable for a "minimalist" effect, but for some customers especially those older people who would pay the price of such an item, poor eyesight in low light conditions is a consideration, while I know most people can tell the approximate time without them, adding things as markers in the mould isn't a difficult endeavor - semi precious stones, shells, small fossils like ammonites, glass hearts for the ladies - maybe with different coloured ones for the quarters would all both add interest and make it easier to see, all of which can be bought in bulk from ebay for very little money.
The desk lamp, while also very well made is just downright overpriced for all but the chelsea / knightbridge set, and I'm not saying that to be cheap, far from it - my personal family background is one of moderate wealth, but it is still just a desklamp, that no-one I know would pay for, and also having spent some time in a salvage / upcycled / repurposed furniture quirky items shop with designer prices, has taught me that some things, no matter how inventive or unique simply don't sell above a certain price point, regardless of the effort involved, because people simply do not care how long it took to make. I'm also a bit diasappointed that you have chosen to show the cord, although maybe considered a feature in red, it shouts out against the "minimalist" lines of the whole. If it were I I would make the arms in 2 halves with a channel for the cord routed out before gluing those 2 together, but that's just me. Instead of having a clunky (plastic - for £350 REALLY??) clicker maybe look into having a touch stud in the base for on and off?
I'm sure you have spent the time looking at the plethora of desk lamps available around the same price points as comparison, but a quick look myself has shown for the same pricer range you can buy beautiful antiques, old industrial ones or ones with more features.
I'm no expert but I'd imagine that many startups make barely more than minimum wage (if that) until established, it seems like you are expecting far more from this initial period than is warranted.
For the selling side of things I'd echo contacting boutiques and companies that deal in the refurbished antique / homecrafted items market. As has also been said a smaller margin of profit in the hand is far better than the much bigger forcasted one - something echoed by every single one of the dragons from dragons den. While many places like "not on the high street" and etsy have high priced items, what they don't show is volume of sales at that price point.
I'm really not trying to be negative but give you my honest thoughts to add to all the others, the more feedback you have the more you are informed.
oh, as an afterthought - as you have the moulds have you considered using casting resin with inclusions?
