CSS / PHP Information sheet required - maintain my website

I have many small amendments that require fixing (approx 24 - most are the same) these amendments are so annoying and frustrating simply because they are small tasks but I dont know how to fix them. My site is CSS with a PHP auction script. Rather than giving someone a job to fix my website I want to learn and be able to maintain my auction website myself. The amendments are very basic mainly consisting of allignment, moving, closing gaps etc (Most are them are the same amendments!). I dont want to let anyone in my hosting as my auction site is starting to improve and dont want the risk of personal information being stolen. As a result of this I would appreciate it if someone could look at my amendments, locate the amendment area with chrome or firefox and use the 'element inspector' to locate its hosting path. Once this has been achieved you will then give me directions how to amend once I have located it in my hosting. I have dreamweaver but have never used it.... however I can build basic html websites. My problem is that I cant find what im looking for in hosting. Rather than buying a book on CSS/PHP I would rather pay you guys to jump straight in and give me answers that will help me maintain my website using an MS Word Document. Simply look at the amendments and provide a format easy to follow: For example: Amendments 1: Hosting path: XXXXXXX Step 1: do this XXXXXX Step 2: do this XXXXXX Step 3: do this XXXXXXX I need this fixed once and for all! As long as the document is clear to understand and easily to follow ... document can be any size. Amendments attached! Max budget: £20
