best of luck with opening the shop, when i opened my shop a couple of years ago i got my dad to make my stands, he's a bit of a handy man and did a really good job and it meant that i got what i wanted to fit exactly, made from wood and then painted, looks great and didn't cost a bomb, so if you know and trust anyone that can do this for you i would look into this option. In terms of what you need to organise for the shop opening my best advice is to sit with a pen and notepad and write everything down and then start to work through your list, things like, signwriting, phones, broadband, interior decor how is the shop going to be laid out, sundries, electric, water, till, statonery inc business cards, portfolio, loads of stuff come to mind which is why you need a pen and pad to have a starting point because as you think of one thing it will lead you on to another. hope this helps.
