ONLINE STORE on bitrix platform (CRM Online Store)

It is required to quickly implement the project (selling site) on the Bitrix platform on the basis of ready-made solutions from the Bitrix marketplace - online stores (ONLINE STORE CRM) - Aspro, Phoenix (under discussion).
Theme – sale of industrial electronics.

There are some important features:
- large number of SKUs – high requirements for search speed
- debugging the functionality of the basket (see below)

The TOR consists of THREE parts.
=======================
THE FIRST ("BASIC") PART OF THE TOR includes:
- installation of the license and template for my domain and for the hosting recommended by the contractor (I pay for hosting and the domain)
- minimal "branding" – colors, logo, sliders
- fill in the "test" item to debug the work
- "screwing" electronic payment methods
- setting up a personal account and email notifications for all statuses
- upsell and cross-sell setting
- integration with social networks
- admin panel – adaptation to minimal tasks by the system administrator, minimal training

An important factor is that it is necessary to immediately refine the "basket", as a result of which the functionality of the online store changes slightly, namely:
in the CLASSIC version - the user collects the basket and CAN PAY IMMEDIATELY.

We NEED: the user collects the cart, finalizes and sends the order, in response to the user from the store manager comes (soap, personal account) ACCOUNT (the account can be adjusted by prices and availability by the store owner) - and only after that the user pays.

The SECOND ("additional") part of the TOR consists of:
- turnkey launch of a bundle of CRM (Bitrix24) and an online store - leads, transactions, etc.
- "bells and whistles" associated with various interactive services, for example, delivery calculation
- SEO

The third ("final") part of the TOR consists of:
- Integration with 1:C
- "fine" settings and screwing additional modules (solutions from the Marketplace, Business Processes)

Lets start working with the first BASIC part.
The main thing is efficiency, compliance with deadlines.

TO GET STARTED, YOU NEED TO DO IT
=====================================
1. Links to READY-MADE, WORKING IN THE NETWORK your works implemented on the Bitrix platform (just a link to the portfolio will NOT SUIT YOU).
2. Specify whether there are skills in the installation of the solution "ONLINE STORE CRM"
3. Based on the task to offer (solutions) templates that, in your opinion, are suitable for the implementation of this functionality, and with which you have experience.

If everything is OK - we send the TK, you study and offer approximate terms and cost for the development of an online store on a ready-made solution, taking into account improvements.

SECURE TRANSACTION OR DIRECT PAYMENT (a bank transfer with a contract is preferred)

============================================================
ATTENTION: WORK "BY THE HOUR" IS NOT EVEN CONSIDERED!!!!
