Improve Site Performance

Hi, We have a social community website. Its on a shared server. The site loads slow. The images, the icons, and the features too inside. When u click from page to page, or on options site a bit slow. Also imp features like uploads, and the loading of images on the pages takes time, thus making the site performance not optimal. As of now just 20-30 users only daily visiting. 1-2 pages esp the home page loads in parts, and pieces with he borders etc loading in parts and thus making it look pretty shabby. Not sure if the cache problem, or image optimization problem, or a coding issue - or all 3. Need some one good to urgently see this and sort this out in a day or two. Should not be a major job and in all probability is a clean up work. Can give u the login details as soon as u bid. Only Experienced & Reviewed vendors/consultants/experts kindly pls bid. Will take it forward accordingly. thanks
