Hello there,
My name is Bojan I am freelancer from Macedonia/Europe.
I can help you out to build an extension for your Magento store
I am not working by my self, I have 7 other colleagues working with me 9AM-5PM at my office.
We will be available for any questions, plans or explanations about the whole process.
So far we did a lot of extensions, mostly custom ones (not for Marketplace) and they are integrated with the website frontend/backend. If you want to see some, please let me know I can send you some examples.
All code that we are doing, is followed by Magento standards.
So no hardcoded solutions, no errors, no core changes. The extension that we will build will be separate and compatible for all Magento 1.9.+ versions.
Please visit my Freelancer profile, as you can see most of my projects are Magento and there is a lot of happy clients.
I hope you are the next satisfied client.
Looking forward to get back from you.
Best Regards,
Bojan
