The best way to go, in my opinion, is to buy yourself a good weighing machine. I don't know how much fragrance you want to make at any one time but it is possible to get some electronic scales which are accurate down to 0.1gm, and with these you can make 100.0gm samples with ease. Forget the drips and drops, weighing is so much easier and more accurate.
Mixing your finished fragrance with alcohol is, again, pretty simple. All you need to make a fragrance that can be worn as a cologne is aromachemicals, Essential Oils, Absolutes and resins, and Perfumer's alcohol (and you don't need all of these when starting out). When you have finished making your concentrated fragrance, simply mix it with alcohol (between 10.0 and 20.0% depending on whether you are making a strong Perfume or an Eau de Toilette), and leave it is a cool dark place for a couple of weeks. Then filter it, using, if possible, a good lab type filter. Some people advice using a little water, I have never done this. Do not uses "carrier oils" (such as Jojoba) as you will have all sorts of solubility problems. If you need to use a solvent (to dilute down very strong aroma chemicals, or to dilute very viscous materials for ease of compounding) use Di Propylene Glycol (DPG).
Accurate notation is vital. Every trial you make, every idea you try out should be noted down. As you learn about the behaviour of Raw Materials (how long they stay on the smelling strip, how strong they are, how they behave when mixed with other things, what they smell like to you) you should make notes to remind yourself. When compounding I always worked in percentages (in grammes) so my formulation would be written as a list of Materials, with the amount (in grammes) written against each one. This would total 100.0.
Hope all this is of some help; and good luck.
