desktop link to website

Hi, I am looking for someone (not sure the exact skills required) to produce a simple icon/s that a user can download from my clients website and put on their desktop, and when they click it it takes them direclty to their website. Ideally it/they would also be able to be emailed to clients as part of the preopening marketing campaign. I already have an exe file with an embedded icon, which is fine for windows but am looking for one for the Mac/Ipad and if not too expensive one for Android as well. Have attached what I have so far (incl exe file), the design is also included, so am really just looking for someone to produce them. Obviously the problem I have with the exe file that is included, is that it cannot be emailed (maybe a simple link in the email might be the only option) without zipping, and much the same for downloading from the webpage, it needs to be zipped when downloaded and then dragged to the desktop. Again maybe that's the eaiest (cheapest) way. All the rest of the details I can provide when needed. I would like the option to not progress with the job if the cost is too dear, as I actually have no idea what the cost is to be honest. Anyway hope makes some sense and Thanks. Greg D.
