I will happily pay someone to sort this out for me.

I have created my own website using microsoft publisher 2003 and was wondering if anyone knows how i can clean up my html code.
It views correctly in ie7 but with the images taking a while to download to the page, but does not view correctly in firefox.
I have done a w3c html validator and it says i have 203 faults with my source code.
Can anyone give me any advice as to how to sort it out. I'm not very good with html and any help would be appreciated.
Thanks
Lee
