Historical dress trousers

My partner (an embroiderer more than a seamstress/dressmaker) has been preparing to work on a project of making a pair of 1890's style morning dress trousers for me in a particular fabric. However, we now fear that we won't have the time to complete the project, and I thought I might reach out to you to see the project through?
I have the intended basic pattern from Black Snail Patterns, but of course this will need adjusting to fit me (for example to ride historically high at the waist, and to taper correctly in the lower leg) - we were looking forward to working this out for ourselves but it now seems we won't have the time.
We have already purchased the fabric (an amazing grey and lavender herringbone) and we can send this to you if you are happy to work on this with us!

Please let us know the price and ideal timeframe,

All the best,
Olly and Miranda
