    I am seeking a skilled web developer to create a very small college admissions consulting service website that incorporates membership functionalities and purchasing capabilities. I have a logo, domain, payment integration and bank account authorizations, and a full script for the website pages. I need a basic website that describes my service and my one product and allows customers to pay me through the website. I also need a page where viewers can subscribe to get access; on the members-only page they can view or download a pdf file that I created. I am flexible about the visual design / color scheme but the logo is already done and has a specific font and RGB custom color. Any images or content used on the site needs to be copyright-free. The goal is to keep the site simple and allow two things to be purchased - my time as a consultant and my pdf (to view on the site or download). I do not have accounts at platforms such as WordPress or MemberPress yet - I need to find a designer first. The entire website and its contents need to be copyrighted to my business name or to my name. I need the website to be functional and published ASAP. The scope information shown below only allows me to choose '1 - 3 months' but I believe this simple website project will take less time.

    The bot is to ideally work on ctrader with the bot written in ctraders built in platform cbot. Potential returns after optimisation to aim for 7-11% ROI YoY. Running times will be established after optimisation due to manual back testing playing a large part in the success of the bot.

    The idea of the bot is that it is actively monitors the prices points of some of the most popular technical analysis (TA) tools and indicators.
    Each TA and indicator is assigned as being either major or minor. Each one is considered a confluence.

    The bot will actively monitor for when the different major and minor confluences become within a set price range of each other. The alignment in price of multiple confluences at once is what creates a trade signal.

    The bot should draw technical analysis precisely to specific parameters to avoid false readings

    Ideally the bot will have the capability of being “customisable” possibly through a user interface. This aspect should allow for the bot to only search for specific major and minor confluences that are selected. This will allow for intensive back testing.

    Parameters for position sizing, stop loss levels and take profit levels should be fixed but customisable. Trades should exit upon a trade signal for a counter position.

    Hi! I’ve built the early version MVP of a Shopify app that lets merchants:

    ✅ Import reviews from AliExpress for their products
    ✅ Manage reviews from the Shopify admin panel
    ✅ Display reviews and star ratings on the storefront product pages

    Now I’m looking for a developer to help improve or rebuild parts of it, clean it up, and eventually expand it with more features — like post-purchase review collection and additional widgets.

    I don't have massive budget, but I understand that 100$ won't be enough for it.
    So I am open for negotiations to try to work out a deal that would work out best for both of us.
