Hi,
I can design your brochure, sticker and envelopes for you for the bid of $250.00. My bid also includes researching the best price for the printing, and directing you to the best on-line printing service for your project. I can also provide the service of ordering the projects for you, but only after acquiring the quotes and everything will have to be paid in full in advance.
You should be made aware though, that most full color printing, especially with things like perforations and diecuts (the windows on the envelop) require higher minimum orders than 150 units. Also, since the envelope is printed on two sides, and also has windows on both sides, there is a high probability that it was printed and die cut before conversion (folding and glueing) into an envelope, and generally, quantites in the thousands are required before the price per unit is even close to reasonable.
I would be happy to research and get quotes to find the smallest minimum quantities available as part of my design bid.
I'm a professional graphic designer, with over 30 years experience in the printing industry, and I look forward to putting my expertise to work for you,
Daria
