Slow Internet webApp

I've finished building my webapp but the location where it will be mostly used has really slow internet.
I was thinking if I should connect my server to their network and put apache and php on it and connect it to the db on my dedicatedserv (so it won't only be accessible on the network)

What do you think?

Because that's what the company called it "Companies Name webApp" and I can't change the name of it.
