Adjustments to Tumblr theme

Hello, I want some customizations to this Tumblr theme: [login to view URL] It has to be a flat design one page website (so everything listed has to be on the same page) The things I want done are: - Option to add menu items on the top that are linked to corresponding to the items on the same page. As is now with portfolio. - The links at the projects tab should pop-out (not a pop-up) in the same window with something like the js lightbox effect. Then there should be the option to scroll left and right (also show clickable arrows to the side to make this clear) to go to previous and newer posts. - The links that can be placed at project should be endless and have a load more option - All menu's etc should be editable/addable/removable from the tumblr menu (no coding) - There should be two extra fields (like follow us) (with menu buttons on top) Where we can add content to with the normal post option in tumblr. Maybe with a special tag so that all the posts with this tag show up there. - A contact form with captcha (preferebly recaptcha) - Links clicked on the top slider should have the option to open in a lightbox as before or go to another page (like our facebook page) The page structure should be: - Social links (without so much spacing and has no menu item on the top) - Music (normal post) - Videos/Pics (project post) - Shows (normal post) - About (normal post) - Contact (contact form) If anything is unclear please ask! My aiming price is $40 Thanks in advance
