I'd love to help you out, we use an online invoicing system that gives you a login where you can keep track of all invoices, pay them, print them, etc. Take a look at our portfolio http://www.sevencube.com/portfolio.php#logos and if you feel we're on parr with the quality you want - give me a shout.
I don't know if you are still in the market, but KMLV, inc. is registered and licensed in Nevada. We have an entire separate division within the company that is dedicated to web design / print design / branding. If you are still interested please feel free to contact me and we can discuss pricing and i can send you some stuff from our portfolio.
