Build an Online Store

Hi, I'm an aspiring web entrepreneur working to build a shopify store. I'm looking for some very quick help to get a proof-of-concept store live. I'm having a logo designed, and should have that available in a few days. For now we can use a place holder. I'd like help for someone to build out basic store front. One featured product which will be a free sample box of 5 fabric swatches. If someone likes the swatches they will have the option to buy sheets in one of the 5 options, in 2-3 colors and in 4 different sizes (Twin, Full, Queen, King). I can complete the copy and do the photography. For now please just use placeholders. I'd like help designing the fonts of the store and getting the navigation and placement correct. What do you think? Would any other details be helpful? Thanks, Mike
