Access database in the cloud?

Hello Freelancers. I'm looking for someone who can suggest a solution to a puzzle/problem, and help us get started in the right direction. Here are the details. We are a small manufacturer's rep business. We currently have an highly developed, custom MS Access database application that is the heart of our business information, handling everything from orders to commissions to forecasting, advertising and promotions, and more. It's a split database with users accessing the front end by logging onto our server (Windows 2008 R2) via remote desktop/terminal services. The back end (Access tables) are also on our server. We recently migrated to Office 365 for email, file storage and collaboration, etc.,, but users still have to log onto the server to get to our data, run reports, etc. We'd like to try to find a way to fully transition away from the server. The problem I'm facing is that trying to convert our existing database application over to a Microsoft "web app" would be a huge project that I'm not interested in. We'd have to try to replace all our VBA, for one thing, let alone re-creating 50 forms, over 300 queries and reports.... I'd like to find a way to keep our existing front end if at all possible, and migrate the tables somewhere "in the cloud" so I don't have to maintain the server in the office. I recently tried making a hybrid system with Office 365, importing the data into a web app, and then linking our front end (on each user's local desktop) to the new SQL tables that were created. But those tables don't maintain referential integrity, so we started seeing duplication and errors right away, and also the performance was really slow. I think it was probably not the right solution. I would prefer not to build a whole new application on a proprietary system like Caspio. Partly because of the work involved in starting from scratch, partly due to the monthly fees, and partly because if they go out of business, I'm out of luck. Someone told me the best solution would be to put the data online using SQL tables and building a website to access it using PHP, but I don't know PHP at all and don't have time to learn. I like understanding the application myself and being able to make changes as needed, but I own the business and I should be spending most of my time selling, not programming. So I am looking for an easier solution if it's out there. I looked at Amazon web services, wondering if they might offer an environment or any tools that would work, but I don't even understand the different terminology I see there, so I don't know if there's a solution there or not. So basically I'm looking for ideas on how to do this in a way that would minimize our development time, and keep expenses down. My problem is that I don't know enough about development, networks, SQL, etc. to even know if there's a good solution out there. I might just be paying for your advice. Here's my proposal. If someone can suggest a solution that works for us and that I can implement all by myself, I'll pay $75 for the suggestion - so your great idea and brainpower won't have gone to waste. If it's a solution that requires your assistance (most likely) for us to make the transition, I'll pay your hourly rate. Let me know what you think.
