I need a new website for ecommerce

I need a new website. I need you to design and build my online store. I'm Elizabeth and I want to build 2 MAGENTO ecommerce sites for my grocery store and online pharmacy store both stores are startups based in Lagos Nigeria, Africa. I want to build it from scratch and it will include product images upload, descriptions, payment gateway integration, web hosting on cloud servers. I will also want to work on both the front end and back end for this projects. I will also make the freelancer expert that builds the ecommerce sites to also maintain it into the future. Both stores are startups and it is common knowledge that startups are lean on finance so please kindly give a reasonable and affordable quote. Let us have a full quotation including everything you will do for this project and all the things included that you will provide and then we know the things that are excluded so we can understand what is to be done exactly. Also how long will it take to get completed. Both online stores will be done at the same time so that we can launch both stores at the same time. I hope we can get capable experts that can handle many projects together. I look forward to hearing from freelancers soon. Thank you. Lizzy.
