Hi there, fellow blender user! I'll keep this short, as you have said you are short on time, and there are a lot of bids to look through.
I've recently completed a few similar projects with some simple rotation animations, and I am confident I can do what you need here as well.
I will definitely need more references, and higher resolution images, in order to model the chair itself, which will be the most time consuming part. I can also texture everything and render some still images or animations, whichever you need.
You can find examples of the above-mentioned projects on my profile, which you can use to judge whether you think I will be able to do what you need.
I look forward to hearing from you and working together!
Best regards,
Tyler.
