Development of wordpress plugins for customized stickers

I am looking for a developer to create Wordpress plug-ins for a website selling customized stickers on a Woocommerce basis. I am looking for a developer to create Wordpress plug-ins for a website selling customized stickers on a Woocommerce basis. I am attaching a draft layout which must be respected both from a graphic point of view and in terms of functionality. Once the work will be confirmed, a starting theme, to be agreed together, will be chosen and purchased and the final layout will be sent with the related .svg files. The part we need to be created is that of customizing stickers (already mentioned in the layout). The rest of the site will be created directly by us. The maximum deadline for the plug-in delivery (already installed and functioning) is for September, therefore it must be usable within and not beyond 1 month. The basic functions must be the same as those of these two case studies: [login to view URL] [login to view URL] Once the work will be quite completed, the graphic materials and the main layout will be provided (all in .svg format) and they have to be respected as soon as possible. We strictly require to respect the following characteristics on the realization of the plugin: 1) It must respect all the required technical functions and the characteristics of the graphic layout provided 2) The layout must be responsive and adaptable both from mobile and from PC 3) It must be integrated with the checkout and payment functions of wordpress and woocommerce. 4) It must allow to download the customer's customized order directly in pdf (preferable) or svg. 5) The plugin must be stable and able to support related changes to the page layout. 6) The preview must be updated in real time 7) it must have the possibility to insert icons or flags independently (always with .svg format). 8) The script must be able to last over time despite the various Wordpress CMS updates 9) The work must be carried out starting from a theme (preferably Enfold) or from one chosen concurrently 10) The work must be carried out satisfying each requested part and respecting the pre-established budget, for this reason I'm looking for professional programmers able to complete the work in every single part (this is due to negative experiences previously we had). If something is not clear, please contact us and we will try to answer all your doubts as soon as possible. Thank you in advance for taking the time to this announcement.
