Here's an example of why most freelancers fail. The answer that will help you land more work is the last one.
Why respond with questions if you don't even know if the client can afford you? Wasting your time.
Why respond with costs/avail without asking any questions too? That sounds uninterested.
Why ask for a meeting when you know nothing about the client or if they can even afford you. That's wasting everyones time.
If you learn to respond with your general costs, availability, and ask questions you're knocking out everything the client would ever want to know within the first email wasting no ones time but the 2-3 mins it took to respond.
For those that say "you can't give costs without knowing what the clients want"...well...you sound inexperienced (which is ok but it's time to starting learning). Everyone should know their rough pricing. By saying it, it's not a contract. It's a starting point to a discussion and the most perfect way to weed out clients you don't want.
And don't think for a second the client only reached out to you. They always reach out to several especially when you're in a certain bracket and it's the first one that gives the right answers and communicates the quickest and clearest that wins.
But go ahead, keep asking questions and never telling the clients what they want to hear. Just means more work for my friends that know how to close the deal.
