Build an Online Store - Preferably with Prestashop

Hi everyone! I need to quote the development of an online store for a clothing&accessories boutique. My client is thinking of something with 50-150 products. I need this to be ready for review in 2 weeks of less. Please send examples of other stores you've created. Don't did if you're not ready to communicate on a weekend (no, we don't want you to work 24/7 but we might need to ask a question / make a comment every now and then and should we need a 9-6 employee we'd hire him/her to have him/her available... so you should be available). 24 hs to have a 10 mins chat is too much. Aside from that, we'd be really grateful if you could send us your portfolio/links to previous work + estimated time it would take you to accomplish the project. Please tell us how much would this cost us and also how much would it be for monthly maintenance (making sure the website does well with platform updates & uploading/downloading products.. never more than 50 products a month.. It's a tiny boutique). Speaking SPANISH is highly appreciated so if you do, please tell us! Cheers!
