New guy here, looking to have an ecommerce website build

I am looking to create a real estate website that will not access any type of MLS service. The site will contain real estate listings that realtors pay to post. I would need to have a backend setup where realtors would have logins and would pay a membership fee to post.

Once logged in, the realtor would be able to post information to a profile and setup property listings. I would need for the property database to be searchable and possibly accessible from 1 or 2 other sites that I would have created at a later time (if possible).

The appearance of the website should have a professional feel and the website itself should be able to handle a large amount of traffic. If possible, I would also like to, If possible, I would also like to have it setup where it will be able to convert currency and measurements to fit the viewer's preference. I do have some other additional site add-on requests as well, but would like to start with this and see what the cost would be, then proceed from there

If you're interested in this project, just reply to this post or PM me

Thanks!
