Sell my artwork online and make commission

I need help selling my paintings online. I make miniature artwork and I am wanting to sell some of the originals. For every painting you sell, you will get a percentage of the amount. Eventhough there isn’t a strict time-frame or deadline, I would like these sold as quickly as possible. There will be oppertunity for this to be an ongoing job for you if you manage to carry this out to a high standard. There will be a minimum sale price given to you for each one, but if you feel like you are able to get more for it, you can do so. All photos and details of each painting will be sent to you for you to use to sell them. If you are interested and feel like you’d be able to do this, please let me know. Thanks
