Time spent creating our product

Firstly, for the sake of my sanity I am not going to even THINK about trying to estimate how many hours I have spent on the software so far... that could well be too disheartening. However, the basic details are:
I started the process of designing it on April 6 2009,
the design document, which was created in tandem with writing the software itself, went through 18 iterations - so far,
at least 4 other people have been involved in reviewing the design and making suggestions,
the first saleable (is that even a real word?) version of the product was available on about June 25 2009,
our website was first put up on about May 1 2009, went through a serious revamp for June 17 2009 and needs review again when the new logo is finalised and the planned additions to the website are implemented,
determining a reasonable costing model was a full time job for about 10 days - finding costings for competitor products (and checking which really were competitor products and which were not really competing for our potential customers) was the largest part of that time,
the web browser accessible version (which will be easier to sell) has been started about 2 months before it was planned for - which is great - but is still estimated to be 3 months of work,
a trainer has reviewed the online Help documentation for the software,
testing is progressing,
brochures have been created along with a PowerPoint presentation for the product,
a couple of videos are being scripted and then need recording,
the product has been presented to two Business Consultancy firms and one potential customer,
word of mouth is starting to spread the information that the product exists,
we have a (very) basic business plan and marketing plan, but both need fleshing out,
we have no real documentation processes for the business yet - receipts are being kept but not recorded, invoices are sent and cross checked when payments appear, but this needs more structure,
oh dear - some of that is the business rather than the product - but at least it gives some idea on what has been involved so far.
