Really Needed

I need a new laptop. This one I'm using for my business is almost 10 years old and is having trouble using newer applications. My problem is the laptops that are commercially available do not fit my needs. I am looking for custom laptops. I saw somewhere that there are a few specialty stores online that custom laptops or laptops that can be customized to a customer's needs.

I have to do my research before I decide. I need something that would help me with my business and I need it ASAP.
