Urgent WordPress fixes + 1 page — live tonight (Expert)

The site is 95% complete. This is a small, well-defined finishing job — essentially one new page + its form, an email fix, and some tidying up. Not a big build. It just needs doing properly and fast: everything must be live and working by 22:00 GMT today. Please only bid if you can commit to that deadline.
Scope of work:

Fix the contact forms (critical). None of the site's forms currently deliver to my inbox. The domain runs on Microsoft 365 / Outlook, so the site needs authenticated email — WP Mail SMTP with Brevo (or similar) is preferred so no Outlook password is shared. I need live test submissions that I can see arrive from every form on the website as confirmation.
Build one new "In Studio" page + its bespoke form. I'll provide the complete design and the bespoke multi-step form (HTML/design supplied). Implement it faithfully in WordPress so it matches the design and submissions are captured and emailed to me (working, tested).
Minor form changes. Some small changes to form drop-down boxes (I'll specify exactly what).
Typography & text QA. Check every page uses the correct brand fonts consistently and fix any wrong/default fonts. Brand guidelines and fonts provided.
Spacing & alignment. Tidy up spacing/alignment issues I'll flag.
Mobile optimisation. Ensure the site — especially the new page and form — is fully responsive on mobile.

I will provide: WordPress admin access, the complete page design + form, brand fonts/guidelines, and the mailbox address for form delivery.
Payment released on: every form on the site delivering a successful live test email to my inbox, the new page + form live and working, and confirmed correct on desktop and mobile.
