asking for a price for my idea

Many weeks of business plan development, website architecture, etc. I arrived to a website business in vancouver which ask me 20 000$ to make my website. I had just find a new job this week, am I going to put all my extra from my income in the idea I believe. Every day at that time was running in my head. I talked with a friend which is in the same time my brother in law. He offer me to make the graphic for me, but on the other side the company was not interested to have anybody from outside their business... so after another discussion with an higher director from the company the price was range at 50 000$. It is no way I can get this I though had that time. So my friend Manu had some colleague who can help us to develop the project. The design was great, after many discussion at long distance via internet we develop the idea. The programmation was behind. That was in july and we was expecting the website for october. My job was to guide the website and plan the marketing. All the money that I have to invest will be in marketing and business set up.
