In fact, since you can't afford to pay anyone to do it for you, you have to do marketing yourself.
Writing a decent product website isn't that hard.
For motivation, start by reading http://successfulsoftware.net/2013/10/16/marketing-hacking-t...
Then learn the basics of marketing (it's not rocket science) and apply the things you learn in practice.
If it's B2C / mass market B2B then sure, a website can do half of the job; but there are huge markets where even they really like your product and they call you, then 0 sales will be made unless you get a sales rep in their office.
1) Sell 2+ or more of the toolset to get some working capital
2) Promptly hire inside sales on 1099 to get out there and get the business with base salary. I've been assured the time & effort to find someone with commission-only offers is futile.
