Definitely doable but like someone else mentioned, since it is probably on the city right-a-way, the city may have to get involved. I did mine two years ago and had to get the city to inspect it after I had it formed and before the concrete was poured. They had me cut into the asphalt street a couple feet further to get to unbroken asphalt to make a straight union and it had to be six inches deep. They also had a specification on the psi of the concrete that it had to be minimum to ensure garbage trucks and other city vehicles wouldn't break it up right away.
Assuming you have an area maybe 12 or more feet wide by five or six feet in length and six inches deep, I personally would skip trying to do it yourself with a cement mixer and buying all the sand and cement in the right quantities to do it. It is quite a bit of work mixing it properly and getting the proper certified strength. I would do the busting up and forming of the pad myself and just have the mixed concrete delivered and poured. You will have to do the leveling and troweling but that it fairly easy to learn how to do by watching videos. Every concrete place I've ordered concrete from has a trowel that they will rent to you for a few extra bucks on top of your concrete purchase.
