Blu-Ray on normal DVDs

Hi, I make wedding videos and have had my first request for the finished film to be Blu-Ray. I don't possess a blu-ray burner and as I am closing my business and this will be my last job then I do not want to spend a lot of money on hardware I will never use again. I recently saw an article that said I can burn HD video to a normal DVD using toast with their Blu-ray disc plug in. Does anyone know anything about this.
My recorded footage is on: Sony Ex1 , shot- HQ 1920/50i, edited in FCP7, pro-res timeline. My computer is an iMac and I burn my DVDs on a sony external DVD writer.
My question is - does this really work and what quality could I expect. Also as everything seems to have it's pitfalls I wondered what they would be in this case. Any thoughts, advice or insight as to the working process on this would be much appreciated. Regards BRIAN

Thank you for Juan your reply. Do you know if the quality is as good as that of a blu-ray disc made with a dedicated burner. I normally only make DVDs using iDVD. I output a disc image which I use in conjunction with toast to burn the disc. Can I do the same with burning an AVCHD disc or do I have to output a blu-ray file first using something like compressor. Is there a recognized standard working practice that is best.
Finally how short should the content be to work fine. I read somewhere that a standard disc could hold up to 1hour but 40 minutes was the recommended max. after which quality would suffer.
Finally one last question - when I make a normal DVD from 50i footage I never deinterlace and on a normal television there are no jaggies. However, never having made a disc to be played on a blu-ray player to be shown on a high def television set I don't know how it will look if I do not deinterlace. Will I see jaggies if i do not deinterlace or will it be smoothed out in the same way that a normal TV does.
I would do some tests myself if I had a blue ray player and high def TV but sadly I do not.
Many Thanks BRIAN

Expect playback to spotty if it plays at all on older Players. But since youre leaving the business who cares? :) Seriously, the best way would be to borrow or hire someone with a burner.
