Want to hire eCommerce specialists

Hello all.
I am working on upwork.com.
But I have too many projects and clients. I feel short in time and need to get help and assistance.
Sometimes I need partner developer who can collaborate with me on several projects.
Basically I need to build trust and it's done by some projects.
Hope to meet good developers( show me proof of work you done).
European developers are preferred( I work with European clients in EEST time zone).
