Help me to find some customers

Hello everyone. My name is Mauricio and I am Visual Designer from Colombia. I worked on some projects here in Freelancer but lately has been dificult to get win projects on this platform ... Currently I have an office job to live but I would start making a living as a full-time freelancer. I'm not very good with sales and marketing, so I could not do anything but find projects here ... I want to start collecting customers and prospects but I have not enough time to do this. Your work will look for companies and customers in developed countries willing to pay a fair price for my (it will be cheaper for them) for professional work with high quality standards guaranted. Currently I have an old portfolio of 2 years ago but right now I'm working on building my personal brand ... I can not put a link to my page because it would violate the rules of Freelancer, but I'll attach a PDF document with a Excel file with a tariff or price list with the standard design values ​​here in Colombia ... These prices are in COP (Colombian pesos) but you can use a calculator to know what the amount in US dollars. The idea is that you can use this price list and my portfolio to attract new customers. Your profit will be 10% of the value final agreed with the client. I hope I was clear, please put in your bid "Hello Mauricio" to know that you read all this description. Regards.
