Ask HN:Should I Optimize my website if I plan to rebuild it?

I have a website at http:://www.safeb4sorry.com the person who originally developed it did not do a great job at programming / optimization. Though I am not the best programmer I did dabble in coding a while back so I know that it wasn't done that great. I plan to pay a real developer to go in and change it once I get the funds together.

Should I optimize the page still even though I plan to change it, or should I wait until its been re-developed?

The Domain Name will stay the same.

Thanks,
