I m a website developer with over 3 years of experience.
I build website with such various frameworks and templates, like yii, codeigniter, expression engine, cakephp also cs chart,, bootstrap, foundation.
I had seen this two websites, and read the requirements. For the first search feature, it will be fixed, yes, with passing variables in url and also can encrypt it for secure it.
For the second problems, i think,, it will change the database,
if you want just have same name task, it will just easy with give another ID in your database.
But can i first look your pages, so i can tell you if it's hard or not to make it one task for more than one person, it can do, and more logically to be done.
My goal is to always provide best quality work in a very short time and keep my clients expectation reached. WIlling to work with you, and do my best in our milestone, i have responsibility to do work as i promise even if i will give extra time to work or other requirements or features in developing.
I really appreciated clear work scope, schedule, and payment.
And nice to know you,, regards,,vivi
