Comments:
1) We realize all details are not posted herein. Please give us a decent estimate quote or hourly rate and we'll send you more info.
2) Most of our projects require custom programming skills, not just open-source script installations. Please don't bid on the project unless you can actually custom program the script and accommodate the changes we will most likely have after the project is complete.
3) We have worked with many outside providers. We pay in stages via escrow as the project progresses. I'm afraid we will not deviate from this policy as we rarely have had a project finished when paid in advance.
4) Before hiring a provider, we require a proposal showing a timeline for completion of each stage of the project. We ask that the timeline be accurate and that all work be done in timely fashion. Do not provide the timeline with your initial estimate since you won't know all details and I don't want you to waste your time.
