Agree with the above posters about just using some generic formulas to start out with. Since you mention you're new to biking chances are you will need to adjust your position as you get more in shape from riding. A pro bike fit at this point would be a waste of money. Get your fit in the ballpark, go ride and once you get plenty of miles in look at what feels uncomfortable, awkward or painful and then report back here for advice, experiment with changes or see a pro.
