Ajax PRO needed for general fixes and tweaks of current ajax

i have a website consisting of a few javascript and jquery with ajax functionalities on most pages (10 pages). the current ajax functions work mostly but I need smaller adjustment and bug fixes from somebody who knows more about ajax than me. example of fix: I have a div with yellow fadeout effect when a new item is created. however the effect works only on 1 div at a time. however i need sometimes several divs to display the fadeout effect. its urgent: delivery 1-2 days max since the site needs to go live.
