Help with Wall Cutout Opening

What I'm wanting to do is do a cutout in the wall (like this: http://s3-media3.ak.yelpcdn.com/bpho...jeYz7ejA/l.jpg).

I have this wall between the kitchen and the living room. It spans about 20+ feet as shown in the pictures on the living room side, and about 14+ feet on the kitchen side. I want to put a cutout with a countertop in it near the door (between the kitchen and living room) that is about 5 feet wide and 3 feet tall.

I am fairly certain it is a load bearing wall because the joists run perpendicular and cross over on top of this wall. This wall runs the span of the entire single story ranch right in between the two supporting outside walls. The house sits on top of a crawlspace.

How big of a lvl beam do I need to support this cutout?
Will I need to do anything extra in the crawlspace to tie in the jackstuds?
Depending on the size of the lvl beam, is there a requirement to the size of the jackstuds being held up by the lvl beam?

Thanks!

 

Not going to work in your favor trying to get free engineering advice on any web site.
Way to may variables, and to much to risk.
Something like this will require an engineer to sign off with plans and a permit.

 

Have to agree with joecaption1. And I see at least 2 permits-- structural & electrical.
