Gmail Addon

I'm looking for someone who can build a Gmail addon or Chrome extensions, similar to Streak.com. I am not sure if the app needs to be either or both. - A quick background on this idea Currently for work I have to make line budget and quotations with a large excel spreadsheet, then export it. I also have to also include other elements of word docs and so forth. And then combine all of these pieces into a single PDF quotation for my customers. I would like this app to avoid all of the software and programs on my computer and keep everything in the cloud when making these quotes/PDFs for customers. So it would all be located inside gmail from the start and be a very quick and fast process to get a budget and quotation to a potential customer. We could choose from different templates and then once you have finished and have it completed then you can simply have one button for export and it inserts the finished PDF into the original email and it’s ready to send to the customer. Another app that functions similar to this is [login to view URL] Please visit and see how this works. I also have other requirements, but I am not sure how to relate them visually. - I will want to make sure that it's setup on the ecommerce site for selling on subscription, so needs to be able to cancel the subscription if they fail to pay. - Will need to also track the emails - Will need to keep PDF/quotation/line budgets organized that we send to clients. So when we make a new version, it will automatically number it for the next version. We will also need to go back and access older versions should we need.
