If you are useing the glue as the paint medium applying the design directly from the bottle to the screen Aleene's Jewel It glue is a thin body water proof glue that flows nicely from the bottle. It is bluish in color until dry then clear and doesn't discolor with age or exposure to the sun as some glues will.

An online store whether wholesale or retail would need to obtain a unique domain name, a hosting account, some payment processing/merchant account to automate the acceptance of credit card payments.
Maintaining ownership of a domain name is one form of business name protection, I would think a wholesaler would probably be setting up some LLC or corporation to protect personal assets.
If the traffic were modest a simple $8/mo "unlimited" shared hosting account with a bundled domain name might do for starters, I can't recommend a particular source they are countless.
Having the site created with your catalog pages, shopping cart software and payment/checkout processing would have to be created, ther are lots of web developers out there, if you provide a very specific requirement you can get bids from freelance developers on sites like Odesk.com or Elance.com it's possible to use off-short talent to save money, more ideally you use a local developer you can meet face to face. It's possible to start with a design template to save on development cost,
One of their hundreds of retail templates can probably be adapted as well.
Getting known might require a combination of paid internet advertising and search engine traffic which can be boosted with SEO. Getting visitors can be the biggest challenge.
Some wholesale sales go on at marketplace sites like Ebay or Amazon, which also help provide prospects. This can be a simpler way to test the waters. A simple online retailer might also use a dedicated estore host with integrated templates for an initial test store.
Eventually you might be able to get into "certified" wholesaler directories like WorldWideBrands.com
