Finalization of the online store on Bitrix

Good afternoon!

I am looking for a responsible person who will help in bringing the online store to mind. Middle will cope without any problems at all, June should also, if there is experience with Bitrix. So the qualification is not so critical, but the experience of working with Bitrix should be.

There are many tasks, although all of them are not very large. Here are some of them, the most critical at the moment:

1. Part of the goods from 1C is unloaded in kg or pieces, but at the same time in 1C there are packages (for example, chocolate in kg, but you can sell in packs of 2.5 or 20 kg only). Package information is uploaded as storage units by a directory (highload block). It is necessary to link the goods with this directory and make the appropriate automatic recalculation of prices

2. Processing of product cards for our needs (adding non-standard requisites, combining some details into one (for example, a description for TP), displaying additional information for a number of goods manually by non-standard output)

All work is carried out on the test server, then they must be transferred to the prod.

Plus, there are a number of small tasks, but important for us.

I want to find a person who is ready for a relatively long cooperation, and not for 1 time and then disappear. Payment is individually negotiated.
