If you have a (La)TeX problem, please try a TeX newsgroup, forum or related site, such as TeX on StackExchange or the LaTeX Community Forum. I'm currently not taking on any new TeX consultancy contracts. (Check the TUG list of consultants for other professionals.)
The Dickimaw Books imprint is a sole-trader business not a publishing company. If you want your manuscript published, I recommend you find a literary agent or try self-publishing.
If the shop is closed, then it's likely that I'm out-of-office and possibly offline until the designated reopening date.
