tcpdf expert required

We need an expert in TCPDF. Please review the attached php document and PDF output that this produces. We need you to change the script so that it makes the following changes: 1. The top logo needs to move up the page by 26px 2. The SKU, PRODUCT, PRICE, QUANTITY, SUB TOTAL need to be vertically aligned centrally 3. Reduce the height space in between each item in the table by 12px 4. Looking at the screenshot attached ([login to view URL]), the bit shaded in RED needs to appear at the top of each new page 5. The SUB TOTAL, VAT, DELIVERY, GRAND TOTAL, address on the left (which is generated with ), and notation on the right (which is generated with ) should only appear on the last page of the PDF (where there is more than one page). The content from above should never overrun into this page. 6. If there is a second page and the products ordered overrun onto the second page then the table header (as marked in green on [login to view URL]) should appear on the second page beneath the header (as on [login to view URL]) 7. If there is more than one page then the footer of every page except for the last one should show the text at the bottom but spread across the whole width of the page, e.g. If it has 3 pages, then is shown in the footer of pages 1 and 2 and ), and would show in the footer of page 3 (as it currently displays) 8. Currently when on the second page (as on [login to view URL]) the footer text appears to close to the footer. It should display the same distance that it does on [login to view URL]
