Nice start to your site . . . it looks like you changed the folder name to your contact solution, which should be fine depending on the editor you are using or your ability to hunt down and change links accordingly.
Your spry (field validations) are visible because they are not linked correctly to their spry data functions (at least that has been my experience). And the CAPTCHA is not showing most likely because the proper folder isn't being referenced.
I would redo the contact page (using the contactus.php file) and not change the folder name. Get it to work first. Then, if you have dreamweaver, you can change the folder name with the only caveat being that you accept all name changes.
As for the responses so far . . . continue to try and be patient because php is frustrating to the new user and communication between non-php users and php users is difficult at best. I'm not much better off than you, but I think I can help you here.
Get a fresh copy up (no folder name changes) and we'll go from there. I check back frequently . . .
