Hello!
I recommend to look into third party solutions. Due to your marketplace niche you can choose one of existing CMS (content management system). For MVP please look to wordpress CMS (wordpress.org). You can easily roll-out it in default design in 1 day and you can split the audience on register page. For different group of customers you can enable different functionality. I've launched several marketplace MVP on wordpress and then when the hypothesis confirm hired dev.team and develop my one platform.
