Website copywriting then ongoing article and blog writing

Hi there, we are a consultancy company specialising in marketing and business development, revenue generation for global venues and hotels in the business events (conferences/meetings/corporate events) space. As our focus is on developing and activating their strategies, we've had no time for ours. So here is what we need and I have attached our budget for each aspect so please let me know if workable. Stage 1 - We need to update and refine our 4 business units, 2 of which require new copy or a refresh. Marketing & New Business (traditional/digital/content/experiential and Sales Representation - We have a budget of $AU15 for each unit ($AU30.00) which is an intro paragraph and 2 paragraphs for each. I will be able to provide copy for rewrite to enhance understanding of our business. On success of that, we have an ongoing opportunity. Stage 2 - Establish a blog on our wp site that is to be integrated that into facebook, twitter, linkedin. Topics will be advised though recommendations welcomed but always around sales, marketing (including digital) for hotels and venues. Also content marketing incorporating video production. This will be ongoing. We have a budget of about $AU15 p/week for 2-3 blog posts on above topics. This will be a 1month trial period then ongoing if successful. Stage 3 - Article writing - For online and print for trade press. We require on average 2 x 500word articles per month. Each one will be checked thoroughly of course. Our budget for this ongoing opportunity is $AU25.00 pending word count. Please let me know if you are interested in the project either as a one-off or an ongoing. We would prefer an ongoing arrangement building trust and a partnership moving forward. Kind regards, landrews
