We currently have a site that has customer sales (metalforhire.com), however, it is not nearly enough for any investor to risk their money on. We do have some big ideas for the site, but at this point we need financial backing to get there.
We had hoped to provide our own finances with the initial Product, it just is not bringing in the profit we had anticipated.
Are we better off proposing the "Big" ideas to investors separately than the already created Product?
Investors want companies, not products. If you have a road map of several products (and how they fit together), show them the first one as an MVP with realistic forecasts, clear understanding of the product/market fit, user acquisition plan, and deep knowledge of the cost to acquire a user and lifetime value, you should get some attention.
While the overall advice from John is correct, he got one thing super wrong: he shouldn't have been so flippant about the answer. "why is this even a question?" It's a question because most people weren't born with the know-how to launch a start-up, that's why. Props for asking, how else will you learn the answer? Best of luck!
Why is this even a question?
If I'm going to invest my money in one of two people (an idea person or a doing-it person) who do you think I'd give my attention to?
Now if you actually have something and can demonstrate that it fulfill a need that is not being met then it's subjective to how much money and time it'll take you to get to the point where you're able to make the sales to start paying me back. In that case go as absolutely far as you can go before you even think about approaching an investor and when you do you should have already asked yourselves the questions that investors ask people. Ultimately if you don't have sales either what you have isn't in demand or you must absolutely justify why you're convinced and dedicated towards what you're working on and make it clear you've made as much abundant progress as can be made sans investor.
