Migration to Flarum from a 2006 platform

HiThere

I would like to migrate a current installation of Vanilla 1 (yes, one!) to Flarum.
As I'm getting older and no longer have time/patience to fiddle with things I don't/want to understand, thus won't/can't learn, I'm looking for someone to do it for me.
I'm not sure how much this would cost and if it would be financially viable, hence this post.

Current status:
Dedicated server: https://www.hetzner.com/dedicated-rootserver/ax41-nvme/
MySQL:

MUST:

keep most current structure/style/css, so that the transition doesn't provoke any "don't-like-the-new-look" allergy on our users
rewrite current custom URLs to new URLs with all the correct 301 redirects, so that we can keep our ranking on Google

"Need to have features" AND OR need to keep database of:

like/agree post
thank you post
upload and display multiple images + PDF
user favorite discussions
user favorite saved searchs
no answer discussion filter
sink discussion
user profile custom page (user can provide a custom two column table of data, for example, Phone | Number, Site | www.site.com, etc.)
report to moderation
private categories based on roles

"Would like to have" features, actually not present:

best answer
related discussions
unanswered discussion automated bump, i.e., bump an orphan discussion when there aren't new discussions in x hours or when there's no activity within x minutes, etc.
automated post of new (previously saved) discussions when there aren't new discussions in x hours or when there's no activity within x minutes, etc. (this will be used for news, articles, how-tos, etc. NOT to generate bogus posting)
Facebook/Google login
desktop/mobile notifications

"It would be great if" features (WARNING: buzzwords ahead):

AI spam moderation
AI generated discussion title based on original post text (i.e. summarize) and on rules (x characters, avoid y words, etc.)
AI automatic (predefined and limited) tagging of new discussions
based on above, suggest OP to consult or append to existing discussions rather than create a new one

I'll provide:

a server to do whatever you need to accomplish the migration (no access to live server)
a comfortable deadline
remuneration based on stages

I'll donate 25% of the migration service price to Flarum (100% for the migration service + 25% for Flarum)

Feel free to comment and add anything you think it's worth here.
I would love to hear some input.

Looking at Nitro Porter by @linc, a former Vanilla dev, it supports Vanilla 1 as a source for its migration functionality (linc/nitro-porterblob/main/src/Source/Vanilla1.php). How much of your requirements are actually implemented will have to be seen, but it would be a great starting point.

Looking at the amount of data in your tables, it doesn't seem to be a massive amount to deal with. I think the biggest complexity lies in actually migrating all your required things and extending Flarum to support all your needs.

Regardless of looks modified by Css, users will know immediately when the migration happened. Many settings and interactions with the app will have become massively different. Masking them behind some make-up will not hide the actual change from the public.

I can come back to you coming week, I'm not behind a pc right now. One thing I am sure of is that a fixed fee won't be possible, as there are a lot of caveats and unknowns to figure out. I will send you an email coming week and explain our processes etc.
