Selecting Multiple Values from a large list of database

I am working on a website which sells electronic lab products like trainer kit,analog kits etc., It has nearly 600 products and i used mysql db to store the data and retrieve . Now i want to show these products in a page so that the admin can select multiple products at a same time and when he submits it will generate an quotation. I can work with multiple select using checkbox and all, but if i show 600 products in one page it will be bad, so i need to show it in multiple pages . My doubt here is, can i use multiple pages using pagination and select multiple products from different pages using checkbox to get the output or is there any other simple way to it.

I need to select multiple products to generate a quotation , the products list is large, which will be the correct way to do it??. I haven't yet started the design for this page as i am confused on how to present it.

Your help will be much appreciated .
