Quick question is your car NA or Turbo , i am having a punt it is NA by your avatar.
A workshop will be your best bet due to the fact you will get some sort of backup should a fault arise due to installation.
Doing it on the ground is just a major pain in the arse due to the dowel pins freezing in place and require soaking with a good penetrating fluid to assist in removal.
being NA it will be a push type clutch which will make the job a little easier.
with a hoist and someone with a sound mechanical background it will only take approx 3 hours to do drive in drive out.
Make sure you use a machined flywheel whether its yours or an exchange unit or you will be wasting your time and money and will end up with a horrible shuddering clutch that will have a short life span.
Be prepared when the transmission is removed to also find other problems such as an oil leak or such that can be addressed whilst the transmission is out.
