Make mini changes in a wordpress theme -- 2

whoever bids the lowest price & delivers the work faster, will take the project. simple as that. Hello. I am in a need of some mini changes to be done on our website: [login to view URL] attached there are some images with the changes i want to be made Image 1: on the menu, there are some links that images are not working. I think that they are on code but they have an error, or you will have to find suitable images that will fit the website design and add them over there (this is for: Events, Schedule, Contacts. The second problem is that the images that are in the homepage of the website, are loosing so much quality when they are shown on the homepage. you have to fix that. Image 2: On "Our Blog" there is a mess. I want there to show around 16 articles. 4x4. The design of them, can be like the 'categories' in the homepage ([login to view URL] attached on project). Image 3: Find a better image for Facebook that will fit with the other images of social networks that are already there. Image 4: There is a problem with the chatbox. Some times when opening the chatbox with chrome, it does this thing, the website crashes (in the end of the user) and the chatbox is actualy trying to load the website (only in the screen of the chatbox). Those are the changes needed to be done. Whatever questions you have, feel free to ask. thanks
