This is a good one mate. It is ice you are marketing your skills here but I would suggest you edit Thur thread adding your portfolio as stated below bey you so one can easily see them at one upon first glance  rather than scrolling down to check for it as some investors or potential clients do not have that time of scrolling down to start looking for your portfolio and past works. Do well to put them here and also if possible tell your past clients if they are registered here to also vouch for you as they have tested your services as you claimed you have had many deals and jobs in the past. This will speak very well for you instead of much talking.
And lastly, do not fail to seeking the services of an escrow for transparency and credibility if there be any client you are working who have indicated interested for you to work for them.
