Hello there. For your budget I can offer you to install OpenCart - the platform is free and very well developed. Also there is very good support and you can find tons of themes/templates/modules and plugis to install on your shop. It supports literally everything what you want, or what you may want in the future. You can have your shop in one day.
We are interested on your project but we could not get the exact requirements.
Can you provide us with a detail requirement so that we and our team can move forward accordingly.
Thanks!
