We have a very large wisteria that grows on our deck. While we can do maintenance pruning we need some help in cutting it back to prevent damage to our deck rail. Are there in experts that can do this work or give us pointers to we do not kill our wisteria. Thank-you

What you want to do is called hard pruning, rather than twice-yearly maintenance. My information states prune in July/August or in winter. The following information might help if you plan to do it yourself.:
"Drastically shortening back long branches, removing sections of older stems to just above a strong young branch or growth shoot lower down, or cutting completely back to a main branch, or even to ground level may be necessary. A careful, unhurried approach is needed if larger, thicker branches are to be removed and where a branch is twining it may be necessary to trace back and mark it at intervals with string before removing it."
The following website offers more information and a link to a video https://www.rhs.org.uk/advice/profile?pid=242
If you plan to have the work done, I cannot recommend a specific arborist but when you call be sure to check whether the arborist is licensed and whether he/she has done hard pruning on a wisteria before.
Thanks for using as an expert
