I'm very new to NXT (first post) and joined the forum to learn more about listing assets. This thread caught my attention as I know a thing or two about auction sites, and can't see how what you are proposing is possible. so I would like to know what are your revenue projections like? If you are selling 75% of your business (and according to your post using that money for marketing), what's your financial motivation for actually RUNNING the site?
As an example. Let's say your revenue 2.5% on sales, and there are $100,000 a month in sales. So your revenue on that is $2500. Of which 75% goes to asset holders, leaving you $625. I would imagine you have a good few hundred dollars a month in costs, so you might have $300 a month left to pay yourself a salary. Except that in order to run a site with a volume of $100,000 a month in sales, you actually need more than one person employed full time. So who pays their salary?
Imagine your marketing was awesome and you actually managed to have 10x the volume at $1,000,000 per month in sales / $25,000 per month in revenue. After giving away 75% of your profit to asset holders you're left with ~$6k a month for salaries and running costs. That enough? How many employees do you think you will need to support a business of that size? I would say 4-5 at least. So you need $300-$400k a year to cover those salaries. I don't think your revenue (before giving profit's to asset holders) would even come close to covering that amount. So what's the plan?
Or have I got it all wrong and you're paying NET profit to asset holders? In which case things are not quite so bad for you as you can include your own salary (which is what?) in the costs, but pretty dire for asset holders. You either pay yourself no wage, therefore have no motivation to actually run the site, and asset holders get a meager return, OR you pay yourself and your employees a salary and the asset holders get no dividend.
On another note, have you surveyed your competition? Do you think you can compete for their business?
