you need to purchase your own mech before you can make any modifications or upgrades. You'll need a few million c-bills before you look into purchasing your own mech. (between 1.8 mil for the cheapest up to 13 mil for the most expensive)
On the bottom left click on "Owned Mechs" then click an empty mech slot and select Create Mech
