You'll get no better help for any money than here!
There are people on here with all sorts of expertise, from Railway staff to obscure religions, from law to lunacy, and they are all so helpful!
Every time I've put a query on, I've had excellent advice and help, with the right mix of helping you to find-it-yourself and confidence-boosting "goodies". Even one's silliest question is treated sincerely, and politely.
When you've made a start, the more you browse around on here, the better an idea you'll get of how to advance your own studies, and that's a far better feeling than merely reading what someone else has found - for money- for you. If you check, and build from secure factual knowledge at each step, you'll be doing it the right way.
Just think: the amount of time you spend on this search is time spent learning. Most of us can't find a great deal that paid "professionals" can do that the "Big Team" of rootschatter researchers can't have a good bash at. And you'll never finish it ......
....and in time you'll find yourself back on a forum here, helping someone else!
