Is it possible to build the deb packages in house and then upload the binaries to launchpad PPA, instead of uploading the source package and let it build by the build farm ?
Ubuntu – PPA hosting packages not built on launchpad build farm

No it's not possible, as Launchpad only accepts source package uploads for reasons of trust - people need to be able to have the source to what was built, and you cannot put proprietary software into PPAs.
