What we do with a band
Design the best version of the project that fits inside it. Without a band we either over-scope and waste your time, or under-scope and undersell what you could have had.
The fear
"They will just charge whatever I say." A studio that does that has one transaction with you and no second project. Repeat work is the business model.
If the band is too small
We say so, and usually propose a smaller object done properly rather than a large object done thinly.
If the band is generous
We tell you where the extra genuinely improves the outcome and where it would not. Spending more does not always buy more.
