I'd gladly help you. If you are truly eager to create a language, there is no restriction in what order things ought to be done. If you're not acquainted with phonetics (that is: sounds) a good start is to base the language on your proper language's sounds.

I believe most conlangers start with a lexicon, then move on with international phonetics and guide lines. But then, that's my opinion. The kit's guide lines are by no means rules, and create a language on your own terms.
