Interesting read and I will certainly be pilfering some of the advice on here for myself.
My advice for what it's worth and some of it is merely reiterating what others have already stated;
1. Don't despair but the possibility of this turning into a viable business in the timescale you indicate is clearly not viable. Perhaps get some freelance / contract work in order to meet the financial requirements that you have.
2. Sell your products and yourself properly. People that pay this amount of money for designer goods want to know more about their unique product. They want to know why and what makes it unique. They want to know who made it (and sometimes why). Give your back story and explain why you and why your products? I don't get any of this in your website.
3. Get your product in print - A friend of mine got her own simple product in a few good (high end) magazines and turned into a business success almost overnight. Exposure is key but be ready for the traffic in ensuring point number 2 is addressed first.
4. Get your product in the right environments. Try your best to get it into places like Purves & Purves, Heals, designer shops, etc. Yes they are going to screw you in their commission however being realistic they are not going to fly off the shelves leaving you out of pocket and it lets you associate your product with high end retailers, i.e. "as sold in Purves & Purves". It will also massively help you with point number 3.
5. Seek out your local (and national) business and funding assistance;

There will be others and don’t dismiss funding opportunities. There are plenty of small and large schemes which may be relevant to you. They generally expect some output in the form of jobs created and / or safeguarded but it’s certainly worth the phone call to see what is available. They may be able to provide you with some mentoring – this can be a bit hit and miss but at the very least you will get some contacts out of this option.
6. Repeat points 1 through 6.
Lastly - don't be too precious about your ideas or brand at this stage. Be prepared to change names, product design, etc. You can get too fixed on a certain path sometimes and blinker out other options often to the determent of the project. Don't get me wrong, 'm not suggesting that you dismiss your brand but at this early stage be prepared to change direction if it is needed, no matter how small or large a change.
Hope this helps and good luck.
