You may find DIY is a bit of a sticky wicket in this case. The diver may have a contract with the marina, or the marina may want inspections done by a "certified and insured" party, so you may have to use him anyway.
Then there's the diving. In many places you'll pay $10 for an air fill, and $30-50 for the annual "VIP" tank inspection, and another $40-50 for a hydro inspection every fifth year. And, you have to take your tank in and (most often) leave it to be be filled, then make a second trip to pick it up. Depending on your local shop and how local and reasonable they may be, that can be a real PITA. And, the regulator should be inspected and adjusted annually, figure $50-100 at the shop. You can skip this for a while but then sooner or later, there are rubber parts in there that need replacement too.
Of course if you are doing your own bottom cleaning and all, there's more incentive for the investment, and diving itself can be a LOT of fun. "Some assembly required" often applies though.
