Hello
b0yw0nder204,
I strongly recommend ESXi for yor case. You can start with workstation hardware for begining. Later you can add shared storage as iSCSI. When you need more computing power, then you will buy server.
I mean you must grow your IT infrastructure as your business is growing. CAPEX means capital expenses. This is initial costs for buying server, rack, network equipment and etc.
OPEX means operating expenses. This is regularly to give money for support, spare parts, subscription and etc.
CAPEX + OPEX = TCO (Total cost of ownership for full life of your investment)
So, it's better for you to start with ESXi on your current hardware. You can manage all hosts with ESXi with vSphere Client (it's free too. You can download form installed ESXi host from browser).
Next step must be shared external storage. I exclude FC SAN, because of price. I recommend iSCSI storage and you can use your existing network for begining. Just buy chassis with hot plug caddies for HDD. You have MB, CPU, RAM, HDD. Download FREENAS and install it on thata system. Then configure iSCSI target and connect all ESXi hosts to it.
Later you must think for more computing power.
About vSphare licenses - you will decide when it's cheaper to pay licenses and do everithing from one place.
About alternative software for Lab Manager, I think that alternative software will be middle step to Lab Manager.
