I ran a screen printing shop a few years ago for a while and realized that using many different systems to keep our shop running wasn't the answer. We used Google Calendar, Bamboo Invoice, Highrise, Paypal and email which lead to tons of data redundancy and plain 'ol inefficiencies.
After specking everything out and gathering a bunch of initial feedback, I began designing the interface and looking for coders. That didn't work out too well so after a year of that nonsense I bought Michael Hartl's book and started learning rails.
Four months later I was ready to start building Printavo and three more months later I had 90% of it done. To help with the last 10% (Stripe, Paypal and some other bugs) I hired a freelancer (shout out to Kuah!).
Just went live last night and I'm focusing more on the marketing end now.
I wanted to get your guys' feedback on everything, thanks!

If you have some budget you may set an ad campaign and split tests to know what's is working and what is not. You may try several different home pages to see which things perform better. This could give you some ideas: http://37signals.com/svn/posts/2977-behind-the-scenes-highri... http://37signals.com/svn/posts/2983-behind-the-scenes-ab-tes... http://37signals.com/svn/posts/2991-behind-the-scenes-ab-tes...
And also: are you tracking your users behaviors? That may give you powerful insights about the product.
I created an account to test it, but I had several errors in a row: 'We're sorry, but something went wrong.'
For the rest, congrats, it looks great. I hope you the best!
PS: You may work on a better favicon with a relative ease, by now is not looking so good.
