the answer is a little bit late maybe :)) but i still wanted to reply..

The most common mistake by the start-ups are the ambition to do everything by themselves. Being cost-effective shouldn't mean "doing everyhting, in-house or on your own". Spending right amount of money on the right source can make the process more smooth and can help you focus on the correct target as well.

If you are a start-up, don't think that everything counts on only money. Be creative and create alternative business models, which still keeps win-win situation. For example, instead of spending a bulk amount of money on developing a prototype or creating a pitch video for crowdfunding, propose a smaller amount of down payment until the project successfully launched and then give more money or shares as a compensation. I'm quite sure that you will find some professional who are interested in your ideas and can accept this kind of business model.
