Makes make some changes on a magento site

I'm willing to pay $75-125 for this. What needs to be done: Front end: Writing the description for the various pages such as news, privacy policy, company info. I do request a WYSIWYG extension be added in so I can have an easier time editing those pages. The images in the summary pages are distorted, meaning that the images are stretched to fit into a square instead of being proportional size. Is there any way to adjust it to be proportional? Look in the book section as an example. [login to view URL] Item descriptions that were changed in the back end do not update on the front end. I don't know if this is a cache thing or not. The left side category bar do not show up once you get into the furthest category. For example, [login to view URL] Is this a limitation of magento? It would make browsing a particular category a little bit of a hassle if for example, a customer is looking at CDs and want to look at DVDs, but instead of being able to click to DVDs from CDs they would have to click back a page and then click DVDs. The main category bar is still not aligned correctly. Back end: When you click on the product detail items that do not have an image associated with it won't load. I do need the extension that allow changing of attribute sets put in. All the T-Shirts are currently set to default and do not have the option to choose sizes. I'm not going to set 3 separate products just for sizes. The two request for extension is a wysiwyg editor such as [login to view URL] and the change attribute set extension I mentioned before.
