Hello,
We understand that you need a mobile app which will have features of both the site you own. Can you provide a wireframe for a better understanding of the features? We believe you will provide the required APIs for data fetchingand integration. We can prepare a proposal according to your requirements with our final quotation as this is just a cover letter.
We are a company based in India with a team of dot net developers and designers. We have experience in building online stores, job portals, travel portals, saas applications, business websites, portfolio websites, service providing sites, booking engine, taxi dispatching app, mobile sites, mobile responsive websites, etc. So, if you want to see our work we're happy to share.
We believe a discussion about the project will be convenient for both of us to decide anything so if you are interested please get in touch.
Regards,
OKTeam
