Yes but if you only provide web based vpn without any mobile and desktop app than it may not be worth these days. People like to just run the app and surf internet freely not limited to visiting site in I frame. And the most important thing is price try to provide unlimited bandwidth in daily packs which not cost more than 1$ per day. Hope this will help you.
Right now I can't provide an app but if my service gathers steam I will definitely make one for both desktop and mobile users . About bandwidth , all vpns will come without any cap on bandwidth.Pricing I will keep your suggestion in mind while finalizing a price list.
