Variable day rate?

[BlasterBates]

I wouldn't quote two different rates, as it would appear you're gouging on the 1 week contract. The customer sounds as if he could be quite valuable over the long term and as a contractor you will need many contracts with many different clients. If I took my car to the garage I would be pretty miffed if they charged a higher rate for shorter repairs.

If only he was THINKING LIKE A BUSINESS this could be avoided.

How so? I gave a possible option which is similar to the consultancies which get in on a loss leader and then sweep up once they are in. Something for him to consider that's all. The other thinking is charge higher for the short work to make it worth it.

But thanks for your useful input as usual.
