Want to start a business website but...

Wasn't sure where to post this, but I want to start a website for my business and sell my jewelry from that instead of Etsy, but I have no clue where to even start. Where would be the best place to buy a web domain? I would like to have a .com address but I dont want it to cost an arm and a leg, and I need to set up a secure payment system for when people buy stuff from me. Do I also need to know any programming stuff to put it together (I have zero programming knowledge >.< ), I really want it to look nice and professional but like I said I have no idea where to even begin. If any of you guys could help me out by offering advice on how to do this I would greatly appreciate it ^^.

set up a board/forum/blog/website, preferably a board like phpbb and build up from there.

My mom wanted me to set one up for her business, but the amount of work required wasn't worth it. Fuck dat noise. If that's what you want to do, screw automation. Just post pictures of the product and have people manually submit payments/e-mails/addresses/etc.

I doubt you have the traffic such that two people will buy the same item before you have a chance to manually remove it from your inventory anyway.

This will decrease your cost to operate and time to set up drastically. It will save you a metric fuckton of stress, and you'll live longer as a result.

WordPress might work for this? Though items would be sorted by date posted instead of price or anything.
