building a new website

i am beginning to set up my own website for many different reasons. i have my jewelry on multiple selling sites though etsy is the one i consistently sell on. i feel, not think, which may be a mistake, that i need to move away from etsy, not have all my eggs in one basket, to use a cliche, and have my own site. my goal is to sell equally or more on my own site as well as with etsy. some days i question the sanity of it all.
