Remove load bearing wall

[naveenv]

I have a shop in GF and house in 1st floor. The shop has a load bearing wall of 10 feet in length in the centre of shop. I am thinking of removing this wall and introducing a beam and pillar so that I can make it like a full open showroom
1)Need suggestions on how to do this
2) will steel beam and pillar is good?
