I had this same problem but lately I've decided to emulate the model of my Uncle. He has been a fairly successful businessman since the late 70s, with ventures ranging from publishing to travel service to real estate. One thing he always did though was draw in members of the family to help. You'd be surprised how happily people will help you once asked, and being able to step away from a task for an hour or two is a huge relief. Also the quality of advise goes up highly once people become more involved with your business---from the outside looking in, everything seems hunky-dory and you're liable to just have family grin and say "its awesome!" if you ask for their help. Once they've worked on it for a little while too, maybe because they feel they've earned the right to have input they'll tell you what they really feel. This applies to your users/customers too--get buy-in from Day 1 and they'll be the best QA department you ever had. When you have someone right out a 3 page email detailing their thoughts, then you know you're onto something.
