Welcome, to the forum.
You've got some practice time ahead of you for sure. Certification is a bit hard to accomplish at the moment because the rules establishing that process are currently in the public comment period. The FAA released their rules and certification proposal in a Notice of Proposed Rule Making for Part 107 two Sundays back. The comment period for that will last 60 days, at which point the FAA and DOT will review what they received for possible incorporation into and modification of their proposal. It will be a several months to a couple years before the final rule set will be codified. At the moment there are zero centers that can certify you. There are a lot of places you can go for a couple days to obtain rudimentary operating skills, but nobody has an accepted training syllabus yet because none has been published or approved. Any place that offers both some level of multirotor flight training along with course study and sign off endorsement for the Private Pilot written exam are the places that will provide the most benefit for those aspiring to commercial operations.
You still have the option of filing for a Part 333 Waiver but I caution that action until determining exactly what you want to do. The waiver process is time consuming, document heavy, expensive, and requires you obtain a Private Pilot's license. By the time you completed and filed the waiver application and gone through full scale flight training the new proposal could become law. You would have a pilot's license to carry forward but the time and expense would have been a heavy price to pay for something you could have done in a few weeks at far less capital expense.
In the mean time those that want to go pro (no pun intended) might consider reading the study materials for the Private Pilot written exam, with particular attention to weather, airport operations, airspace identification, and collision avoidance. Those points were noted in the NPRM as areas of knowledge tat will be required of an operator applicant. For a shameless plug I'll suggest visiting
www.acuas.org for a one stop location to check out the actual NPRM and link to the NPRM public input comment site. We also have a poll running you can participate in to see what people think of the new regulatory proposal. The NPRM itself provides information relating to what the FAA currently believes will be be necessary to become a certified operator. A back ground check, pass a written test, and register your aircraft are the big three at an estimated cost of under $300.00 for the whole shebang. It also states what they will likely require for operating limitations.
Perhaps a more difficult thing for you will be determining the type of equipment you will need to use to perform the operations you have in mind. What they are used for frequently determines what equipment will be necessary, along with determining the size of the aircraft. Once you have that down you'll need to either buy or build the tools you will be using and practice, practice, practice until you have a clear understanding of what it takes to safely operate the aircraft and all it's accessories. You've come to the right forum for help because most here are either already professionals or very close to it. Although we have fewer people that some sites the maturity of the experience found here is far greater. Nobody is pimping a product simply because they have one. If you get a recommendation for something it was provided because it works. From the aircraft through the payload components the experience level here is high.
