WHMCS custom admin area add order

I want a custom admin area order page which works the same way to the WHMCS admin order page. Differences: - Display list & validation of custom attributes which are set to \"admin only\" and \"order form\" - Use horizontal product listing (similar to invoice style) instead of current vertical products on the left and summary on the right Main Input: - Client ID (just client ID is fine) - Payment Method Dropdown - Order Confirmation checkbox - Generate Invoice checkbox - Send Email checkbox Per product input: (horizontal input, reactive jquery step by step) - step1: Product type (service/product default or domain) dropdown =>For service/product - items to be displayed - step2: Product group dropdown - step3: Product dropdown - step4: Domain name - step5: Billing cycle - step6: Promotion Code dropdown (must be within promo start => end listed under ACTIVE, and expired listed under EXPIRED, must apply to this product group, must apply to this billing cycle) - step7: Addons to be displayed for selection (popup will be ok, but must have button or link to re-display popup) - step8: Admin Only + Order Form custom attributes to be displayed for entering (popup will be ok, but must have button or link to re-display popup) - step9: Price override (optional) =>For Domains - options to be displayed - regperiod - email forwarding - dns management - id protection - EPP code (for transfer) Running totals must be displayed: (ajax/js updated) * Sub total * Discount * Tax lines * Total I will not accept reverse engineered, nulled or decoded WHMCS files which have just been modified. Your code must be somewhat neat and tidy. You must be experienced with WHMCS module development. I need more work done in the future and I need someone reliable.
