I have tried to offer my skills in signature designing but it is so hard to find a customer. I cannot provide them any previous work since I am just new to this forum. I just want to ask if there are any other bitcoin forums where in you can earn bitcoins and how?
Why don't you try to find in altcoin section there are some new ICO releases every week or month and i think you can find some and make your own portfolio that you can offer also in services section for now that is the best you can do because there are Latest ICO releases every week and new signature campaigns
You have lots of competitors in services section you are not the only one who are designing signature so i think better to find it in altcoin section and hope that you can find until you can build your own portfolio and be a trusted. .
