Way to go on the ideas, that's where it all starts! There's a book by Michael Gerber called the "E-Myth Revisted" which I highly recommend. He made the phrase of "working on your business not in your business" famous. You have to realize, and it seems that you do since you've asked the question, that doing is not the same as designing. I'm currently reading a more in depth book by Gerber called "E-myth Mastery", in my opinion invaluable. The most important thing to remember is to focus your efforts on revenue, i.e. marketing and sales. If you've got cash coming in everything else can follow. No cash coming equals not being able to pay the bills, not paying the bills equals going out of business. I agree that infrastructure, systems, financial strategy is important, but not as important as cash flow and from that most importantly profit. Being an entrepreneur means being a leader, of yourself and others, and a lot of the times you're going to feel alone. Don't be afraid to trust your gut after you've researched everything. Shoot me an e-mail if you want to, I'm happy to answer questions. Best of luck to ya!
